tru64 cc does not think that this code is OK:

cc -std1 -DHAVE_CONFIG_H -I. -I../../xforms/image -I../lib -DMAKING_FORMS -I../lib -I../../xforms/lib -I/afs/rocq/home/preval/common/include -I/usr/local/include -g -c -MD ../../xforms/image/image_gif.c  -DPIC -o .libs/image_gif.lo
cc: Warning: ../../xforms/image/image_gif.c, line 672: The scalar variable "incode" is fetched but not initialized. (uninit1)
        flush_buffer(im, incode);

Indeed, if I read process_lzw_code correctly, the variable incode is
not always initialized. Since I do not understand what it stands for,
I cannot propose a fix, but obviously this needs to be fixed in some
