  A couple of things jumped out at me from that text file:-

>newlib-1.82

  I don't understand this. Surely gcc-2.95.2-core is a subset of what's
in gcc-2.95.2, so that step should be unnecessary? (And I'm assuming that
85 is a typo for .95)

  The reason for this would be that the drive on which you're doing
the build is mounted in text mode, most likely. If you have a binary mode
mount point in your cygwin setup, you can create a build directory there,
and it should work fine.

  This will come in handy! Thanks!
