Once the dust settles, yes, I think something should change. The gcc
toolset, using a Cygwin compiler, picks up the Cygwin POSIX emulation
layer and effects how many libraries get compiled/implemented. For
example, it causes the Boost.Threads library to build using pthreads
instead of Win32 threads. I think this is at least misleading, when it's
reported as a "Windows" compiler. The question would be, then, whether or
not the Windows regression report should only be using gcc-nocygwin, or if
it maybe should be using both toolsets.
