Under 4.3BSD, there is a <sysexits.h> which does include a bunch of
standard return values like EX_USAGE, EX_NOPERM, and others, for use
as arguments to exit(); it is not complete, in fact it isn't terribly
large. In any case, there is one return value EX_OK commented as /*
successful termination */ with the value of 0... it is NOT documented
in the comments at the top. It doesn't seem that many people use
these, are they a really recent development? If it were in common use,
the problem under discussion wouldn't be so severe...
