Turns out that I have both libgif 4.1.6 and libgif 5.1.0 on my system.

In some juggling of LD_LIBRARY_PATH and INCLUDE_PATH, the gif_lib.h of
v5.1.0 got read, but the libgif.so of v4.1.6 got used (even though the
newer v5.1.0 libgif.so was in the LD_LIBRARY_PATH too).

To fix this, I moved the "-L/path/containing/5.1.0.so" *before* the
"-L/path/containing/4.1.6.so" and this issue got fixed.

After this builds fine properly, I will move libgif/libungif 4.1.6
completely out of LD_LIBRARY_PATH and INCLUDE_PATH (not sure why libungif
doesn't exist for 5.1.0).
