I just started trying to build m- and s-  files for the Intergraph
Clipper and ran across a code sequence in malloc.c that assumes that
if SIGTSTP and SIGIO are defined the system is a BSD4.2 system and
defines BSD42.  This is so that defines surronding the limit warning
code will work correctly. Unfortunately, the clipper has SIGTSTP and
SIGIO, but not BSD style limits.  I would propose that this code be
changed so that the guess check only be done if "config.h" wasn't
included.  Context diffs are:
