If you upgrade your X11 to the latest on macosforge (or wait a bit for 
it to become part of a software update), I bet you won't be able to 
compile at all. See my query earlier this week titled "Problem compiling 
XEmacs 21.5 (beta29) with latest libpng (1.5)." It appears that some of 
the code in glyphs-eimage.c relies on deprecated structures:

Here is the error I see:
gcc-4.2 -c -Wall -Wno-switch -Wundef -Wsign-compare -Wno-char-subscripts
   -Wpacked -Wpointer-arith -Wshadow -Wmissing-declarations -Wmissing-prototypes
   -Wstrict-prototypes -Wdeclaration-after-statement -Wunused-parameter -g -O3
   -fno-strict-aliasing -arch i386 -I/opt/local/include -Demacs -I.
