* ssp.c (help_desk): Fix compiler warning. Christopher Faylor <cgf@redhat.com> 

Change appropriate globals to statics throughout.
* cygcheck.cc (usage): Simplify usage output.  Generalize to allow use for
help.
(longopts): Add version option.
(opts): Add 'V" version option.
(print_version): New function.
(main): Accommodate new version option.  Accommodate usage parameter changes.
Use usage to output help message.
* Makefile.in (CXXFLAGS): Add override so that HAVE_DECL_GETOPT is defined.
(libbfd): Use -B rather than -L so that bfd from build directory is correctly
found.
(libintl): Ditto.
