+Summary: libgdiplus fails to build on GCC 4 without libgif
+Description of Problem:
+There is a mismatched function definition between gifcodec.h and the #ifdef'd portion of 
+gifcodec.c that's compiled with no giflib is available. Under GCC 4.0, annoyingly strict rules cause 
+compilation to fail at this point.
+Steps to reproduce the problem:
+1. Check out libgdiplus on a Mac OS X 10.4 system, with GCC 4, and without libgif
+2. ./autogen.sh
+3. make
+Actual Results:
+gifcodec.c:611: error: conflicting types for 'gdip_save_gif_image_to_file'
+gifcodec.h:24: error: previous declaration of 'gdip_save_gif_image_to_file' was here
+Expected Results:
+Should compile without errors.
+How often does this happen? 
+Every time.
+Additional Information:
+Changing the definition of gdip_save_gif_image_to_file to take an unsigned char * instead of a 
+char *, matching the header and the other implementation, gets this to compile.
