* README.win32: Update gcc build instructions. Mention gettext is GPL. * gdk/win32/gdkcursor.c (gdk_cursor_new_from_pixmap): Get correct supported cursor size with GetSystemMetrics. * gdk/win32/gdkfont.c * gtk/gtkfontsel.c: Guard against some font weight and charset symbols being undefined (in mingw32 headers). * gdk/win32/makefile.cygwin * gtk/makefile.cygwin * gtk/gtkthemes.c: No longer need to have differently named gcc-built DLLs when using gcc-2.95 and -fnative-struct.
