This version of gcc requires a newer binutils than defined as current in
the Cygwin repo, so until this gets corrected one needs to manually
switch to the test version binutils-2.31.1-1.

Sorry, looks like I have the test version already installed locally.
I'll update binutils ASAP.

Can you please update these as well:

- mingw64-x86_64-gcc-core
- mingw64-x86_64-gcc-g++

They are still sitting at 7.4.0, now two major version behind.

If someone writes a new C project for Windows, they might prefer to release
a Cygwin and Mingw version, but given the current situation thats not possible.

In order to compile cleanly the last snapshot with gcc 9.2.0, i had to apply the following patch (see below).
Otherwise one get an uninitialized variable together with a missing __attribute__.

Thanks, I fixed this a bit differently.  Would you mind to send unified
diffs in future (diff -up is the nicest)?  They are easier to read than
the standard diffs :}


Thanks,
