Hi

gcc sends warnings & error messages to stderr, not stdout, which is what
DOS pipes to the file.  To do what you want, you need to use the `redir'
program (should be in your \bin directory), with something like:
  redir -e make warnings.foo

I'd double check the command ordering, since I may have that the wrong
way round.

Cheers

Dave
