I erroneously moved the use of i386/t-mingw-pthread to the cygwin case.
The following patch should correct this.  Could you give it a try?

Thanks.

  As I just discovered!

  That's not quite right (although it will probably work):

  Notice how in your additions, you prepend the t-mingw-pthread file to the
list in $tmake_file rather than append it as the existing code does.  Ordering
of t-* files in $tmake_file is significant as there may be overrides and files
should be listed from most generic to most target/os-specific, so please
adjust those two hunks to match the way it's already being done.

  OK with that change.

    cheers,

Huh?  I've done it exactly the way it had been in gcc/config.gcc before
my patch series:

        case ${enable_threads} in
          "" | yes | win32)       thread_file='win32'
            tmake_file="${tmake_file} i386/t-gthr-win32"
            ;;
          posix)
            thread_file='posix'
            tmake_file="i386/t-mingw-pthread ${tmake_file}"
            ;;
        esac

Why should this suddenly be wrong in libgcc?

  Hm.  Well, it must have been inconsistent when it was added there in the
first place, so I guess since it hasn't been a problem yet there's no need to
fix it now.  Patch is OK as-is then.

yup, seems to do the trick, n.b., this is on cygwin, not mingw32/mingw64.
