Thanks for this information.  I don't see anything out-of-line.  I
know you need pthreads for libgomp.  The issue I'm having is with a
native build of 2.8.1 as it goes from stage to stage when using xg++
from prev-gcc/ and once from gcc/ with xgcc the compiler options don't
tell the linker where to find the libraries and crt2.o.  I've been
copying them into the build directories to overcome the issue and
continue but I've yet to find a solution to the issue.  I may need to
work on the config/i386 files.

I'd like to put v4 in our master branch sooner rather than later and build the runtime in-line with gcc. Haven't yet figured out how to run 3x and 4x side-by-side for i686-* but we could add x86_64-pc-mingw32 without too much trouble (assuming that's the triplet for 64-bit).

The config.guess/config.sub will give x86_64-pc-mingw64 currently.
That may or may not change.
