DJ already talked about this, so I'll just point out two quick items:

- Make already has a (compile-time) provision for using case insensitive
  filenames, but it breaks implicit rules in a horrible way. Is MER.C a
  C++ file or is it a C file? Does the FOO.F file need to pre-processed 
  or is it really just `foo.f'? Please remember that most of the tools
  are just repackaged Unix tools, and lots of Unix'ism is buried quite
  deep (eg., gcc's use of the filename extensions). 

- Issues like this belong in the general list since this is more of an
  "user tool" issue rather than the underlying API issue.

The Cygwin mailing list has seen this discussion quite a few times before
and should have it archived. It should be pretty easy to provide a command
line or an env variable to choose this behaviour at runtime.
