OK, so my configure-time test wasn't working quite right, and it looks
like SIGC_WORKAROUND_OPERATOR_PARENTHESES isn't working either.

On your platform I think
LIBSIGC_TEMPLATE_PREFIX should be empty,
and
SIGC_WORKAROUND_OPERATOR_PARENTHESES should be sun_forte_workaround

These are defined in sigc++/adaptors/adaptor_trait.h. Maybe you could
check their values and hard-code them to check that it would work.

It's very difficult to do this without direct access, but I'm fairly
confident that it's possible to get this working on Sun Forte C++ 5.5.
Thanks for helping.
