Well, I took up the concept; I didn't see enough of Krazy Glew's code
to steal, and I picked different names for the globals [of course :-(],
argcnt and argvec (I figured "environ" was good enough for envp).

I know what you mean.  Well over half of all the calls to perror() I
write look like perror((char *)0); because the prefix is more
complicated than a single string, so I have fprintf(stderr,....);
before the perror().  Wish perror() were printflike, perhaps like
syslog() - syslog() accepts a printf format, except that %m means
insert sys_errlst[errno].
