i am trying to make xfmail 1.1a, and when i do make, it puts -Werror on 
the end. -Werror isnt in the Makefile, and i need to get rid of it 
because of this:
pork% make
cc -Wall -O2 -I../compface -DFACES -I/usr/X11R6/include 
-I/usr/X11R6/include/X11  -DHS_MADVISE -I. -I../mail -I../pixmap 
-I../editor  -Werror  -c child.c
cc1: warnings being treated as errors
child.c: In function `exec_child':
child.c:203: warning: variable `pnum' might be clobbered by `longjmp' or 
`vfork'
*** Error code 1

Stop.
pork% 

this prevents me from compiling :(
can someone help me with this?
