#254 non getopt option parsing broken
on current CVS, when _GNU_SOURCE is not defined, the option parsing function does not work well when specifying multiple options:
$ cscope -ld
Usage: cscope [-bcCdehklLqRTuUvV] [-f file] [-F file] [-i file] [-I dir] [-s dir]
[-p number] [-P path] [-[0-8] pattern] [source files]
the same for cscope -Rb.
AFAIK, outside the GNU world, options can't be concatenated. That's no bug --- it's required behaviour of Unix utilities. The [-bcCd...] part of the Usage help is really just shorthand for the rather less readable [-b] [-c] [-C] [-d] ...
On second thought, Neil, this looks like your changes to option parsing broke this. It was still working in 15.7a, and setting aside whether it was ever properly documented, I do believe we should keep it.
