I don't know.  Actually I thought you were the one who got me to
update some test suite patch to do this ;).  But I don't really
remember.

I was thinking about just renaming them all to add a ".exe" suffix, to
make the clean rule trivial.  Maybe there's some other way to drop
this stuff, though.

It's been on my to-try list for months, but you know how that goes.
