A few changes from char* to void* where appropriate, and removing of
unnecessary casts.
Much more work on const-ifying the codebase. This round involves some code
changes to make it correct. NOTE!! There will almost certainly be problems
on the non-POSIX ports that will need to be addressed after the const changes
are finished: they will need to be const-ified properly and there may need to
be some changes to allocate memory, etc. as well.
The next (last?) big push for this, still to come, is const-ifying the
filenames in struct file, struct dep, etc. This will allow us to store file
names in the string cache and finally resolve Savannah bug #15182 (make uses
too much memory), among other advantages.
* w32/pathstuff.c: Turned convert_vpath_to_win32() into a
real function. This was done so that VPATH could contain
white space separated pathnames. Please note that directory
paths (in VPATH/vpath context) containing white space are not
supported (just as they are not under Unix). See README.WIN32
for suggestions.
* dir.c: WIN32 does not support inode. For now, fully qualified
pathname along with st_mtime will be keys for files.
Fixed problem where vpath can be confused when files
are added to a directory after the directory has already been
read in. The code now attempts to reread the directory if it
discovers that the datestamp on the directory has changed since
it was cached by make. This problem only seems to occur on WIN32
right now so it is lumped under port #ifdef WIN32.
* function.c: WIN32: call subproc library (CreateProcess()) instead of
fork/exec.
* job.c: WIN32: Added the code to do fork/exec/waitpid style processing
on WIN32 systems via calls to subproc library.
* main.c: WIN32: Several things added here. First, there is code
for dealing with PATH and SHELL defaults. Make tries to figure
out if the user has %PATH% set in the environment and sets it to
%Path% if it is not set already. Make also looks to see if sh.exe
is anywhere to be found. Code path through job.c will change
based on existence of a working Bourne shell. The checking for
default shell is done twice: once before makefiles are read in
and again after. Fall back to MSDOS style execution mode if no sh.exe
is found. Also added some debug support that allows user to pause make
with -D switch and attach a debugger. This is especially useful for
debugging recursive calls to make where problems appear only in the
sub-make.
* make.h: WIN32: A few macros and header files for WIN32 support.
* misc.c: WIN32: Added a function end_of_token_w32() to assist
in parsing code in read.c.
* read.c: WIN32: Fixes similar to MSDOS which allow colon to
appear in filenames. Use of colon in filenames would otherwise
confuse make.
* remake.c: WIN32: Added include of io.h to eliminate compiler
warnings. Added some code to default LIBDIR if it is not set
on WIN32.
* variable.c: WIN32: Added support for detecting Path/PATH
and converting them to semicolon separated lists for make's
internal use. New function sync_Path_environment()
which is called in job.c and function.c before creating a new
process. Caller must set Path in environment since we don't
have fork() to do this for us.
* vpath.c: WIN32: Added detection for filenames containing
forward or backward slashes.
* NMakefile: WIN32: Visual C compatible makefile for use with nmake.
Use this to build GNU make the first time on Windows NT or Windows 95.
* README.WIN32: WIN32: Contains some helpful notes.
* build_w32.bat: WIN32: If you don't like nmake, use this the first
time you build GNU make on Windows NT or Windows 95.
* config.h.WIN32: WIN32 version of config.h
* subproc.bat: WIN32: A bat file used to build the
subproc library from the top-level NMakefile. Needed because
WIndows 95 (nmake) doesn't allow you to cd in a make rule.
* w32/include/dirent.h
* w32/compat/dirent.c: WIN32: opendir, readdir, closedir, etc.
* w32/include/pathstuff.h: WIN32: used by files needed functions
defined in pathstuff.c (prototypes).
* w32/include/sub_proc.h: WIN32: prototypes for subproc.lib functions.
* w32/include/w32err.h: WIN32: prototypes for w32err.c.
* w32/pathstuff.c: WIN32: File and Path/Path conversion functions.
* w32/subproc/build.bat: WIN32: build script for subproc library
if you don't wish to use nmake.
* w32/subproc/NMakefile: WIN32: Visual C compatible makefile for use
with nmake. Used to build subproc library.
* w32/subproc/misc.c: WIN32: subproc library support code
* w32/subproc/proc.h: WIN32: subproc library support code
* w32/subproc/sub_proc.c: WIN32: subproc library source code
* w32/subproc/w32err.c: WIN32: subproc library support code
