+Summary: libgdiplus fails to build with giflib3g headers
+
+Description of Problem:
+libgdiplus fails to build if the libungif4 library and the giflib3g 
+headers are present together on the system.
+
+Steps to reproduce the problem:
+1. apt-get install giflib3g-dev
+2. cd libgdiplus-1.1.7
+3. ./configure --prefix=/opt/mono && make
+
+Actual Results:
+...
+checking for DGifOpenFileName in -lungif... yes
+checking gif_lib.h usability... yes
+checking gif_lib.h presence... yes
+checking for gif_lib.h... yes

+
+Expected Results:
+Either libgdiplus should compile correctly with GIF support, or the 
+configure script should reject these libgif headers as incompatible and 
+automatically disable GIF support.
+
+How often does this happen? 
+Every time.
+
+Additional Information:
+Installing Ubuntu's libungif4-dev package in place of giflib3g-dev gets 
+things working.
+
+Although the libraries can coexist, these dev packages are mutually 
+exclusive. libungif4 is installed default on Ubuntu, but the -dev 
+packages are not normally installed and a person manually compiling can 
+easily end up picking the other library's headers when installing needed 
+dev packages.
