Add GNU Guile as an optional embedded scripting language for make.

Browse source 
On configure-enabled systems, configure will detect Guile installed
(using pkg-config, which is how GNU Guile is distributed) and enable
it if so.

On all non-configure-enabled systems, currently, the default is for
Guile support to be disabled.

Support GNU Guile as an embedded extension language for GNU make.
* NEWS: Note the new Guile capability.
* Makefile.am (EXTRA_DIST, make_SOURCES): Add new guile source files.
(AM_CFLAGS): Add Guile compiler flags.
(guile): Add a rule for converting default SCM into a C header.
* configure.in: Add support for --with-guile.
Also, convert the entire file to properly escaped autoconf m4, and
utilize newer features such as AS_IF() and AS_CASE().
* doc/make.texi (Guile Function): Document the GNU guile integration.
* make.h (guile_eval_string, guile_boot): Prototypes for Guile.
* main.c (main): Run guile_boot() to handle main().
(real_main): All the previous content of main() is here.
(real_main): Add "guile" to the .FEATURES variable.
* function.c (func_guile): Call Guile.
* guile.c: New file implementing GNU make integration with GNU Guile.
* gmk-default.scm: The integration of GNU make with Guile uses
Guile itself for much of the parsing and conversion of return
types, etc. This implementation is embedded into GNU make.
* config.h-vms.template: Disable Guile support.
* config.h.W32.template: Ditto.
* configh.dos.template: Ditto.
* config.ami.template: Ditto.
* makefile.vms: Add new Guile files.
* Makefile.DOS.template: Ditto.
* Makefile.ami: Ditto.
* NMakefile.template: Ditto.
* SMakefile.template: Ditto.
* build_w32.bat: Ditto.
* dosbuild.bat: Ditto.
* make_msvc_net2001.vcproj: Ditto.
2011-11-15 Paul Smith <psmith@gnu.org>
* main.c (main): Use %ld when printing DWORD values.
* job.c (new_job): Ditto.
* w32/include/sub_proc.h: Use const.
* w32/subproc/sub_proc.c (open_jobserver_semaphore): Use const.
Fixes Savannah bug #34830. Patches suggested by Ozkan Sezer.
Fixes Savannah bug #34830. Changes suggested by Ozkan Sezer.

GNU make may be built with support for GNU Guile as an embedded
extension language. You can check the @code{.FEATURES} variable for
the word @samp{guile} to determine if your version of GNU make
provides this capability.
GNU Guile implements the Scheme language. A review of GNU Guile and
the Scheme language and its features is beyond the scope of this
manual: see the documentation for GNU Guile and Scheme.
If GNU Guile is available as an extension language, there will be one
new @code{make} function available: @code{guile}. The @code{guile}
function takes one argument which is first expanded by @code{make} in
the normal fashion, then passed to the GNU Guile evaluator. The
result of the evaluator is converted into a string and used as the
expansion of the @code{guile} function in the makefile.
Similarly, there are Guile procedures exposed by @code{make} for use
in Guile scripts.

@subsection Conversion of Guile Types
@cindex convert guile types
@cindex guile, conversion of types
@cindex types, conversion of
There is only one ``data type'' in @code{make}: a string. GNU Guile,
on the other hand, provides a rich variety of different data types.
An important aspect of the interface between @code{make} and GNU Guile
is the conversion of Guile data types into @code{make} strings.
This conversion is relevant in two places: when a makefile invokes the
@code{guile} function to evaluate a Guile expression, the result of
that evaluation must be converted into a make string so it can be
further evaluated by @code{make}. And secondly, when a Guile script
invokes one of the procedures exported by @code{make} the argument
provided to the procedure must be converted into a string.
The conversion of Guile types into @code{make} strings is as below:
@table @code
@item #f
False is converted into the empty string: in @code{make} conditionals
the empty string is considered false.
@item #t
True is converted to the string @samp{#t}: in @code{make} conditionals
any non-empty string is considered true.
@item symbol
@item number
A symbol or number is converted into the string representation of that
symbol or number.
@item character
A printable character is converted to the same character.
@item string
A string containing only printable characters is converted to the same
string.
@item list
A list is converted recursively according to the above rules. This
implies that any structured list will be flattened (that is, a result
of @samp{'(a b (c d) e)} will be converted to the @code{make} string
@samp{a b c d e}).
@item other
Any other Guile type results in an error. In future versions of
@code{make}, other Guile types may be converted.
@end table
The translation of @samp{#f} (to the empty string) and @samp{#t} (to
the non-empty string @samp{#t}) is designed to allow you to use Guile
boolean results directly as @code{make} boolean conditions. For
example:
@example
$(if $(guile (access? "myfile" R_OK)),$(info myfile exists))
@end example
As a consequence of these conversion rules you must consider the
result of your Guile script, as that result will be converted into a
string and parsed by @code{make}. If there is no natural result for
the script (that is, the script exists solely for its side-effects),
you should add @samp{#f} as the final expression in order to avoid
syntax errors in your makefile.
@node Guile Interface, Guile Example, Guile Types, Guile Function
@subsection Interfaces from Guile to @code{make}
@cindex make interface to guile
@cindex make procedures in guile
In addition to the @code{guile} function available in makefiles,
@code{make} exposes some procedures for use in your Guile scripts. At
startup @code{make} creates a new Guile module, @code{gnu make}, and
exports these procedures as public interfaces from that module:
@table @code
@item gmk-expand
This procedure takes a single argument which is converted into a
string. The string is expanded by @code{make} using normal
@code{make} expansion rules. The result of the expansion is converted
into a Guile string and provided as the result of the procedure.
@item gmk-eval
This procedure takes a single argument which is converted into a
string. The string is evaluated by @code{make} as if it were a
makefile. This is the same capability available via the @code{eval}
function (@pxref{Eval Function}). The result of the @code{gmk-eval}
procedure is always the empty string.
@item gmk-var
This procedure takes a single argument which is converted into a
string. The string is assumed to be the name of a @code{make}
variable, which is then expanded. The expansion is converted into a
string and provided as the result of the procedure.
@end table
@node Guile Example, , Guile Interface, Guile Function
@subsection Example Using Guile in @code{make}
@cindex Guile example
@cindex example using Guile
Here is a very simple example using GNU Guile to manage writing to a
file. These Guile procedures simply open a file, allow writing to the
file (one string per line), and close the file. Note that because we
cannot store complex values such as Guile ports in @code{make}
variables, we'll keep the port as a global variable in the Guile
interpreter.
You can create Guile functions easily using @code{define}/@code{endef}
to create a Guile script, then use the @code{guile} function to
internalize it:
@example
@group
define GUILEIO
;; A simple Guile IO library for GNU make
(define MKPORT #f)
(define (mkopen name mode)
(set! MKPORT (open-file name mode))
#f)
(define (mkwrite s)
(display s MKPORT)
(newline MKPORT)
#f)
(define (mkclose)
(close-port MKPORT)
#f)
#f
endef
# Internalize the Guile IO functions
$(guile $(GUILEIO))
@end group
@end example
If you have a significant amount of Guile support code, you might
consider keeping it in a different file (e.g., @file{guileio.scm}) and
then loading it in your makefile using the @code{guile} function:
@example
$(guile (load "guileio.scm"))
@end example
An advantage to this method is that when editing @file{guileio.scm},
your editor will understand that this file contains Scheme syntax
rather than makefile syntax.
Now you can use these Guile functions to create files. Suppose you
need to operate on a very large list, which cannot fit on the command
line, but the utility you're using accepts the list as input as well:
@example
@group
prog: $(PREREQS)
@@$(guile (mkopen "tmp.out" "w")) \
$(foreach X,$^,$(guile (mkwrite "$(X)"))) \
$(guile (mkclose))
$(LINK) < tmp.out
@end group
@end example
A more comprehensive suite of file manipulation procedures is possible
of course. You could, for example, maintain multiple output files at
the same time by choosing a symbol for each one and using it as the
key to a hash table, where the value is a port, then returning the
symbol to be stored in a @code{make} variable.
