[boost] Re: [Test library] wide_string test and wputenv

This is part of a much larger problem... a quick count in the regression tests shows about 300 failures coming from the test library. Most of these are on compilers we usually consider rather broken, but we need someone to look at these failures and either fix them or mark them.

Actually majority of the failures comes from tests for the features that did not get into Boost.Test. They could be disabled for now. I will do that tonight. Gennadiy
