2002-01-01 Tor Lillqvist <tml@iki.fi> * demos/Makefile.am (test-inline-pixbufs.h): Append EXEEXT to ../gdk-pixbuf/gdk-pixbuf-csource. 2001-12-31 Tor Lillqvist <tml@iki.fi> * gdk/win32/gdkgc-win32.c (predraw_set_foreground): Improved error handling. (gdk_win32_hdc_get,gdk_win32_hdc_release): Silence gcc -Wall. * gdk/win32/gdkimage-win32.c (_gdk_win32_get_image): Silence gcc -Wall. Use GDK_IS_PIXMAP_IMPL_WIN32 instead of GDK_IS_PIXMAP in one more place. * gdk/win32/gdkinput-win32.c (_gdk_input_other_event): Silence gcc -Wall. * gtk/Makefile.am (libgtk_win32_1_3_la_LDFLAGS): Add -lwsock32.
