Doh!  I saw the $(foo) in a shell-looking thing and thought the typo
was that it should have been ${foo}.

Given what you say, the patch is ok.

The usual host I use for such cases is cygwin, which is the only host
I know of which is self-contained in uberbaum.  It's possible to
cross-host DJGPP as well, but it's not self-contained and quite a bit
trickier.
