Expand the characters which are legal in a function name, and check the name for validity. Create a type for the function pointer. Convert the last argument from a boolean to flags, to allow for expansion.

When the function is expanded in the makefile, FUNC will be invoked with

the appropriate arguments.
|
|
|
|
The return value of FUNC must be either NULL, in which case it expands to

|
|
created by gmk_alloc(). GNU make will free the memory when it's done.

MAX_ARGS is the maximum number of arguments (or 0 if there's no maximum).

MIN_ARGS and MAX_ARGS may not exceed 255.
|
|
|
|
The FLAGS value may be GMK_FUNC_DEFAULT, or one or more of the following
|
|
flags OR'd together:
|
|

|
GMK_FUNC_NOEXPAND: the arguments to the function will be not be expanded
