Though I've never attempted a build on MSYS, I discovered some time ago
that Cygwin builds are painfully slow. I traced it to the stat() call.
Whatever cygwin.dll was/is doing to emulate stat() involves kernel and
subsystem activity, noticable by watching the System and LSASS.EXE tasks
during a build.
Maybe this has changed, I build on win32 very infrequently.
