2000-07-23 Tor Lillqvist <tml@iki.fi> Win32 build setup: * makefile.mingw.in * pixops/makefile.mingw.in * pixbuf_*.def: New files. * Makefile.am * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw. * gdk-pixbuf-io.c (gtk_win32_get_installation_directory): New function, to get the GTK+ installation directory from the Windows Registry, where the installation program for whatever software includes GTK+ has stored it. Used to avoid having hardcoding the directory where to look for loaders. This function is needed by gtk, too, so it should really be just in one place. Maybe a small static library one level up from here? * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file) * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Open file in binary mode. This *is* standard C. (No-op on Unix, of course.) * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp(). * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use mktemp() and open(). (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname. * pixops/*.S: The Gas from mingw32 doesn't like the .type pseudo-op. Conditionalise on __MINGW32__, but probably should conditionalise on Gas version instead? Or could we do without .type on all systems? * pixops/timescale.c: Use g_get_current_time() instead of gettimeofday().
