Description of Problem:

Hello there,

I just tried to compile package libungif-4.1.0-13 from Redhat 8.0.

Here are some of the compiler messages.

gifinfo.c:163: warning: too few arguments for format
gifinfo.c:80: warning: `Width' might be used uninitialized in this function
gifinfo.c:80: warning: `Height' might be used uninitialized in this function
gif2rle.c:170: warning: too few arguments for format

Here is a patch which fixes the messages.
