a66469e003 Fix interfacing with and remaking dynamic objects on MS-Windows.
load.c (load_object, load_file): Accept an additional argument
 DLP and return in it a pointer that can be used to unload the
 dynamic object.
 read.c (eval): Call load_file with an additional argument, and
 record the pointer returned there in the 'struct file' object of
 dynamic objects in that object's 'struct file'.
 commands.c (execute_file_commands): Unload dynamic objects
 before remaking them, to avoid failure to remake if the OS doesn't
 allow overwriting objects that are in use.
 filedef.h (struct file): New member dlopen_ptr.
 gnumake.h (GMK_EXPORT): Define to dllexport/dllimport
 decorations for Windows and to nothing on other platforms.
 (gmk_eval, gmk_expand, gmk_add_function): Add GMK_EXPORT qualifier
 to prototypes.
 makeint.h (MAIN): Define before including gnumake.h, to give
 correct dllexport decorations to exported functions.
 (load_file): Adjust prototype.
 loadapi.c: Don't include gnumake.h, since makeint.h already
 includes it, and takes care of defining MAIN before doing so.
 build_w32.bat (LinkGCC): Produce an import library for functions
 exported by Make for loadable dynamic objects.

 w32/compat/posixfcn.c (dlclose): New function.
 w32/include/dlfcn.h (dlclose): Add prototype.

 scripts/features/load: Fix signatures of testload_gmk_setup and
 explicit_setup, to bring them in line with the documentation.

19a69bafc0 Support dynamic object loading on MS-Windows.
w32/include/dlfcn.h: New file.
 w32/compat/posixfcn.c: Include dlfcn.h.
 (dlopen, dlerror, dlsym) [MAKE_LOAD]: New functions, in support of
 dynamic loading.

 config.h.W32.template (MAKE_LOAD): Define.
 load.c (load_object) [HAVE_DOS_PATHS]: Support backslashes and
 drive letters in file names of dynamic objects.

14d7654551 Rework the implementation of load.c to increase portability.
It should be sufficient, now, to write a new version of the load_object()
function.  That function won't be called unless we really want to load, so all
checking and parsing is taken care of before that.

5058a94ee7 Expand the loadable object support.
Provide a simple API for loaded objects to interact with GNU make.  I still
won't guarantee that this API won't change but it's much closer to something
that's supported and provides easy-to-use interfaces with a public header
file.

7670c84f77 Implement new "load" directive.
Provides support for dynamically loadable objects in GNU make, as a
"technology preview".
