I haven't created a shared library with GDC, but the shared (.so) files 
on other platforms are known as either dynamiclib or bundle on Mac OS X.
Dynamic libraries are for linking to and bundles for loading at runtime,
for instance program plugins and modules for Perl or Python are bundles.

Using -soname should be equivalent to -install_name on Mac OS X. See:
http://developer.apple.com/documentation/developertools/gcc-4.0.1/gcc/Darwin-Options.html
$ gcc -dynamiclib -Wl,-install_name,libfoo.dylib -o libfoo.dylib foo.o
But my GDC says cc1d: error: unrecognized command line option "-fshared"
