You need to give us more info how you configured it etc.

Here's my configure line:

  $ mkdir <objdir>
  $ cd <objdir>
  $ <srcdir>/configure --prefix=/Cygnus/cygwin-b20 \
    --exec-prefix=/Cygnus/cygwin-b20/H-i586-cygwin32 i586-cygwin32

My guess is that all you have to do is the following:

  $ cd <objdir>/gcc
  $ make installdirs
  $ cd ..
  $ make

The ``make installdirs'' is needed so that the includes can be found via
the complier-directory-relative path lookup.

Cygwin doesn't support enable-threads yet, so it's a noop.
