[Hugs-bugs] problems building on Solaris

[Sigbjorn Finne]

This is a bit puzzling -- I would have thought that 

gcc -shared -fPIC foo.c -o foo.so

would get you there on that platform. Even so, you
shouldn't end up with a duff option (-r).

If you're in the mood for some experimentation, have a
look at aclocal.m4:HUGS_TRY_DYNLINK (and its
use in configure.ac / configure.in ) and try re-creating
those tests manually to find out what's going wrong.
