 A bunch of the Math regression tests are failing on Mingw with linker
 errors about the Regex library. e.g.

 http://tinyurl.com/2ury8gm


 Appears to be related to Regex lib being built as a static librry on
 Mingw, and adding a

       <toolset>gcc-mingw:<define>BOOST_REGEX_STATIC_LINK=1

 to the jamfile for the Math regression tests avoids the problem.

 Also, the build for the math library itself has huge amounts of warnings
 along the lines of

 {{{
 visibility attribute not supported in this configuration; ignored
 }}}

 which seems to be down to the -fvisibility=hidden option not being
 supported on mingw. Removing that option removes the warnings, but i'm not
 sure how to do that for just mingw.
