* README.win32: More text. * config.h.win32 glibconfig.h.win32: Update to match the corresponding generated files on Unix. * makefile.msc: Update with new source files, and gthread library. Use the compiler flag -MD instead of using -D_DLL and "/nodefaultlib:libc msvcrt.lib" in the link phase. * glib.def: Include new functions, drop removed ones. * glib.h: Add comments about main loop and polling on Win32. (In general, it's only for the GIMP's use.) Add Win32 IO Channel functions. Remove the obsoleted old IO Channel stuff (which was in #if 0 already). * giowin32.c: New file. * gmain.c: Include config.h, conditionalize <sys/time.h> inclusion. Add g_poll implementation for Win32 (only for the GIMP's needs for now, it's hard or even impossible to be as clean and generic as on Unix). Implement g_get_current_time on Win32. If threads aren't supported, don't try to wake up main thread's loop. On Win32, use a semaphore and not a pipe to wake up the main loop. * gmessages.c: On Win32, allocate a console window if the standard output handle is invalid before writing to stdout, and reopen stdout to that console window. * giochannel.c: Conditionalize unistd.h inclusion. Some indentation cleanup. * gstrfuncs.c: Include <signal.h>. * gutils.c: On Win32, also check the HOMEDRIVE and HOMEPATH environment variables. * gmodule-dl.c gmodule-dld.c: In _g_module_build_path, don't add the "lib" prefix and ".so" or ".sl" suffix if already there. * gmodule-win32.c: Likewise for the ".dll" suffix. * gthread-posix.c: Conditionalize <sys/time.h> inclusion.
