Solaris port. Currently sees around 200 test failures, mostly related to

Solaris not providing some of the locales that the test suite uses.

Note: This depends on an xlocale (partial) implementation for Solaris and a
couple of fixed standard headers.  These will be committed to a branch later
today.
