[PATCH] OS/390 v1r2 tweaks

[pg...@sweng.stortek.com]

A couple macros that Ms. Brabson :-) had relied on are not
defined at OS/390 v1r2.  This provides alternatives.  I'm
skeptical of the value of "#define NSIG SIGDUMP+1" -- it's
scarcely a useful parameterization since future extensions
to the OS are less likely to change the value of SIGDUMP than
to add new SIG* codes with values higher than SIGDUMP.  It
might be better simply to unconditionally
"#define NSIG 40  /* Present highest signal (SIGDUMP) +1*/"

With these tweaks, httpd 1.3.10 compiles on OS/390 v1r2
and runs if invoked with "http -X".  Curiously, on OS/390 v2r7,
the same executable, compiled under v1r2 runs properly
without the "-X".  Appears, then, to be an OS bug.  Which
emphasizes the question of why I'm fussing with v1r2.
Or why we're still running production on v1r2.
