All the same, you should probably check to see that whatever variables you
choose to key off of don't alter the way your program behaves in other
alternate Windows shells. A co-worker of mine uses 4NT, which provides
UNIX command and shell emulation in a native Windows format. I expect it
has at least $SHELL and/or $TERM.
FWIW...

My console program is built for native Windows (thus does not reply on

So I'm looking for a boolean method which will allow a program to tell
whether it was run from within a Cygwin shell.
A PATH containing colons which weren't preceded by just a single
alphabetic character would be a clue but it wouldn't be foolproof. A HOME
environment variable with no colons and forward slashes would be another
clue. I don't think there is a foolproof test, though.
Both HOME and PATH are translated by the time the non-cygwin program
sees them, though??
$TERM would be set. That's very unlikely when started from cmd.
$SHELL would be a hint, too.
