While I was trying to port latest sed, I have noted that djgpp's resource.h
does not provide rlim_t.  An inspection of other resource.h files shows that
this typedef should be an unsigned long but djgpp uses long.  I was not able
to figure out why djgpp's implementation uses long.  Anyway a typedef of
rlim_t is required to be able to compile certain sources.

Suggestions concerning this issue are welcome.

Juan M. Guerrero
