- consistently support __hpux (which the HP compilers define) as well
as __hpux__ (not sure which compilers set this, but retained anyway)
- fix a typo in the definition of signal(). arguably the codebase should
just be converted to sigaction()...
1. Compensate for h-pox assert brain damage where it gets confused by the
string in: assert(!memcmp(foo, "in", 2)); I miss the h-pox broken compiler,
I had not had to work around it for years.
2. Oh, finally h-pox has random() and utimes(). We don't need our own anymore.
the .DOTLAST primitive by a boolean variable with the same name, this whole
mechanism was broken ... it doesn't save much stat calls but it was wrong.
Thanks to Jason Thorpe for the other shadow-variable fixing patches he
made.
(XXX - This should be an inclusive, not exclusive, list. Later, this
should be autoconfiscated, but keep the internal implementation, since
src/tools/compat isn't necessarily available for use at make's build time.)
arch.c: Don't require ranlib stuff. Not everybody has it.
dir.c: SunOS-4 != Solaris; change #ifdef sun to #if sun && !__svr4__
job.c, compat.c: Don't use 'union wait', use int and the W*() macros.
main.c: Check for uname() == -1; some unames return > 0...
util.c, job.c: Add signal() with BSD semantics for svr4, don't use bsd
sigmask and friends.
