That would be /bin/sh exe magic from the looks of it. It is probably
just trying to find anything with an executable bit set, just like on
Linux.

It's likely that "mode.com" would execute it.

% cd /cygwin/sources

environ.cc- { NL("HOMEDRIVE=") },
environ.cc- { NL("HOMEPATH=") },
environ.cc- { NL("NUMBER_OF_PROCESSORS=") }, // 7
environ.cc- { NL("OS=") }, // 8
environ.cc- { NL("PATH=") }, // 9
environ.cc: { NL("PATHEXT=") },
i.e., the only thing Cygwin does with PATHEXT is convert it to upper case.
