[failure] 21.0-b42 gif

Hi- I build Jareth's gifreader, in preparation for building 21.0-b42. I patched up from b41. It seems as though glyphs-eimage.c expects gif_lib.h, which is no longer distributed with gifreader. Here is my failure: cc -c -v -xO4 -Demacs -I. -DHAVE_CONFIG_H -I/u/craffert/include -I/ms/dist/aurora/include -I/usr/dt/include -I/usr/openwin/include /u/craffert/src/xemacs-21.0-b41/src/glyphs-eimage.c "/u/craffert/src/xemacs-21.0-b41/src/glyphs-eimage.c", line 493: cannot find include file: <gif_lib.h> "/u/craffert/src/xemacs-21.0-b41/src/glyphs-eimage.c", line 521: syntax error before or at: GifFileType "/u/craffert/src/xemacs-21.0-b41/src/glyphs-eimage.c", line 521: cannot recover from previous errors cc: acomp failed for /u/craffert/src/xemacs-21.0-b41/src/glyphs-eimage.c Here is my Installtion
