>Description:
pkgsrc/graphics/libungif does not compile on IRIX 5.3 (and maybe other 
platforms) due to missing definition of EXIT_SUCCESS, EXIT_FAILURE and due to 
wrong variable usage in the code.
>How-To-Repeat:

>Fix:
in order to compile libungif-4.1.0b1 on IRIX 5.3 I had to define EXIT_SUCCESS 
and EXIT_FAILURE, because IRIX 5.3 does not know about it. I did so in 
lib/gif_lib.h, but maybe there is a more appropriate location?

+ #define EXIT_SUCCESS    0

  #endif /* _GIF_LIB_H */

Secondly, there is a bug (wrong variable usage) in util/gif2iris.c. The 
following patch corrects it:
