Better yet, 4.9.2 has been available for a few days now!

For stuff that I am worried about, I run Linux in a virtual machine,
but for every day tests cygwin is great.

I'm having failures for gcc on Windows with the three or four
Filesystem test that link statically. It looks to me like Boost.Build
is missing dependencies, so compiles aren't run soon enough and then
the archive fails. So I'm wondering if the same problem is affecting
Boost.Test. Boost.Timer is also failing gcc static links, but I
haven't had a chance to look at that in any detail.

I've run into the putenv problem, too. I fixed if for -std=c++11 but
now I'm getting a failure for c++ 03 builds, so I've got to reinstate
a fix for that case.
