'cygpath' is indeed a cygwin utility that translates between
posix and msw paths. IIRC, what it does is built into MSYS.

Thanks for figuring that out. I saw 'cygpath' and guessed at
first that we were attempting something that required cygwin. But
now it appears that
  ./libtool: cygpath: command not found
is libtool's way of saying it can't find the compiler, which
would be une drôle de chose.

Probably we're trying to follow the advice in 'local_options.sh':

# [...] in order to avoid the problem described here:
#   http://sourceforge.net/mailarchive/message.php?msg_id=10579421
#   http://sourceforge.net/mailarchive/message.php?msg_id=10581810
# when multiple versions of MinGW gcc are installed.

which explains that puzzling errors may occur if one version of
MinGW gcc is installed in /mingw/ and we try to use another
version installed in a different directory. To avoid that problem,
we have adopted the custom of never installing anything to /mingw/,
and always using something like /MinGW-20050120/ instead.

Wendy--Guessing that such is your situation, I'd suggest you
first try
  $gcc -dumpversion
and if you get
  sh: gcc: command not found
then that confirms it--so try adding the compiler directory to your
MSYS $PATH, e.g.:
  PATH=$PATH:/c/MinGW-20050120/bin
and make sure
  $gcc -dumpversion
returns something of the form '3.X.Y'; then try the original
instructions and see whether they work for you.

If that still doesn't work, then try Evgeniy's step-by-step
instructions below, which seem carefully designed to create
a duplicate installation that won't interfere with your
present MSYS and MinGW installations.

Evgeniy--I think we're generally using this later version:
  binutils-2.16.91-20050827-1
and would assume that it's okay; but please let me know if
it you know that it is not.

Wendy--If you've gotten here and it's still not working, then
I'd suggest following Evgeniy's steps exactly, even though we
may normally otherwise use later versions of these tools.

Let me quote this advice from 'msw_msys.make':

# If you modify MSYS's '/etc/fstab', end each line with '\n', and
# don't insert any '\r' or use any editor that will do that. Check
# your work carefully with 'od -t a /etc/fstab'.

...because we may be using an 'echo' that inserts '\r'.
