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. 2013-05-03 21:09:12 +08:00			`extern int dlclose (void *);`
