I've done some more testing.  It turns out that gnulib _correctly_
rejects /opt/csw/include/getopt.h as incompatible with the current
compiler, if you use autoconf 2.64 (prior to that, if the existence and
compilation checks disagree, autoconf went with the existence check).

The errors I'm seeing are due to the fact that Dagobert is using CC, not
cc, and I think -I/opt/csw/include is a red herring.  In fact, I can
reproduce problems on Fedora 12 when using g++, now that we replace
getopt even for glibc 1.11, to work around bugs recently fixed in newer
glibc.

So I'm working on some patches to allow clean C++ compilation of getopt
(even if they won't be accepted upstream in glibc); and with luck, that
will also fix Dagobert's problem with CC.
