2000-03-04 Tor Lillqvist <tml@iki.fi> * gwin32.c (g_win32_error_message): New function that returns the message string for a Win32 error code. * glib.h: Declare it. * glib.def: Export it, plus g_node_copy. * gmodule-win32.c: Call g_win32_error_message() to get the error message strings. * libgplugin_a.c * libgplugin_b.c * gmodule.c: Remove LibMain functions that were needed by LCC, which is not a supported compiler. * testgmodule.c (main): Test for G_MODULE_IMPL == G_MODULE_IMPL_WIN32, not G_OS_WIN32. * gmoduleconf.h.win32: Remove LCC stuff from here, too.
