Larry,

Are you on 32-bit Windows or 64-bit Windows? I've noted on this mailing
list earlier that there are large speed differences between the two. I
wonder which platform Gene is on. The tr test results are consistent on
Windows 64-bit for me.

I don't quite understand what MINGW32 is doing that makes it ~2 times
faster than cygwin.
