# Okay, here's the problem: On some platforms, linking against OpenThreads
# is not enough and explicit linking to the underlying thread library
# is also required (e.g. FreeBSD). But OpenThreads may be built with different
# backends (Pthreads, Sproc, Windows) so we don't know what the underlying
# thread library is because some platforms support multiple backends (e.g.
# IRIX supports Sproc and Pthreads). Linking all libraries won't work
# because the libraries may be incompatible.
# So the current solution is to attempt best guess linking and exempt certain
# cases. With IRIX, we're going to hope explicit linking to the underlying
# library is not necessary. We currently don't case for pthreads on Windows
# which might be an issue on things like Cygwin. This may need to be fixed.
