Currently the compile fails on the latest mingw (the one installed with the regular automated installer) due to the _tls_init bug the older boost version has, which spring uses.

If someone merges my master branch into the spring master all should be well

This has been fixed since boost 1.45.0 according to the boost trac, but as long as spring isn't updating to that this fix works aswell.

Thanks.
