Your patch works for me on SunOS4.  Thanks.

FYI, the above __STDC__ change does seem to have an effect.  Mainly on
X11 files WRT which clause of #if __STDC__ conditionals gets diddled
with.  The header diffs look harmless though, but I thought you should
know.  I'm not sure whether we want to keep __STDC__=0 for platforms
which define STDC_0_IN_SYSTEM_HEADERS.  Something to think about.
