Following up on this. I don't know what changed recently, but the
performance of my clang under cygwin has improved dramatically. I have
updated cygwin and rebuilt clang from scratch. I didn't do anything
specifically to switch to a statically linked cygwin. I haven't
investigated. Guess: perhaps the cygwin upgrade caused a rebaseall?
