  There is no such thing as "Cygwin's if".  The 'if' command is a bash shell
builtin.  It does not exist as a separate executable.  It can only be invoked
from within bash.

  Ah, right, I think that's error code EYOUARENUTS.... how on earth do you think
you can run a bash-specific shell script in cmd.exe?  The syntax is totally
different.  Not being able to get at "cygwin's if" command is the least of your
worries.

  Yeh, see, cmd.exe also has a built-in "if" command, and it uses an utterly
different syntax.  Whatever it is you think you're doing, you are doing it wrong!

  Perhaps you should elaborate on the real underlying problem, rather than just
showing us a symptom and asking for a cure based on your own unstated false
diagnosis.


    cheers,
