migrating cygwin-mingw-gcc branch

[Christopher Faylor]

I'll be creating a new cygwin-mingw-gcc-3_2-branch as soon as
the main gcc 3.2 branch, which has just been created, has the
ABI patchset applied.

Then I'll create a new gcc 3.2 for cygwin within a few days.
I won't probably won't take cygwin's gcc 3.2 out of "test" status
until the main gcc 3.2 release occurs.

Read the gcc mailing list for more details about gcc 3.2.
