That made my actual test code go through the compiler, but I still
get an unresolved on alarm.  I'm running MPE C.55.07.  Don't know the
C compiler version (that is, I don't know where to find the info.)

Commands used:

ccxl timers.c timers.o $null -Aa -g
link from=timers.o, xdbend.lib.sys;to=timers.bin; &
   rl=^oarls.lib;xl="oraclexl.pub.oracle6";cap=ia,ba,ph,mr,pm;privlev=2

(The superfluous trash is because this is from a canned script.)

It gets me further, but as with most of these things, it can't exist
in a vacuum.  We have an extensive product that builds using the standard
CLI, and the "native" environment is what the software builds in.

However, you may know the answer to this:  Our docs don't mention alarm()
as a valid function and explicitly state that signal() is put there for
ANSI compatibility and that the only way to actually raise a signal is
with an explicit call to raise().  Is that no longer true?  At what version
of MPE, compiler, or other product did this change?

Thanks much, you've been very helpful!

Eric
