Apparently Solaris 10 includes a getopt.h and appears to be GNU getopt

But surely we would now regard that usage as obsolete now? It's been
replaced by -- hasn't it?
CVS still makes use of it bacause we can parse a line like:
cvs -fq -d /cvsroot checkout -P -d newname module
and getopt with a + as the first character of the option string kindly
stops when it reaches the CVS command checkout. We can then dump
everything up to optind:
argc -= optind;
argv += optind;
if (argc 1)
usage (usg);
and reuse getopt, with a new option string, to parse the arguments to
checkout. I don't think users would appreciate having to preceded all
CVS commands with a -- argument.
cvs -fq -d /cvsroot -- checkout -P -d newname module
cvs -fq -d /cvsroot -- update
It's a bit redundant.
