I've figured it out, I think.  There's an external dir command in
cygwin, which
is the file /cygnus/cygwin~1/H-I586~1/bin/dir.exe.

Before I installed cygwin, the
     $ret = `dir`;
in Perl was running the internal NT cmd.exe dir command.  After cygwin
was
installed, my guess is that system() or backticks in perl were actually
scanning
the path to find a dir.exe first (and finding it in the cygwin /bin
directory)
and running that instead of the internal command.  I renamed cygwin's
dir.exe to
cygnus-dir.exe (since I don't really need it) and all is now hunky-dory.

Phew.
