53	# backends (Pthreads, Sproc, Windows) so we don't know what the underlying
54	# thread library is because some platforms support multiple backends (e.g.
55	# IRIX supports Sproc and Pthreads). Linking all libraries won't work
56	# because the libraries may be incompatible.
57	# So the current solution is to attempt best guess linking and exempt certain
58	# cases. With IRIX, we're going to hope explicit linking to the underlying
59	# library is not necessary. We currently don't case for pthreads on Windows
