Thanks for the pointer, Igor.  That was extremely helpful.

I just ported the test app to mingw.  The only thing I had to change was
to put an #ifdef in to use GCC-style inline assembly instead of
MSVC-style when it looks at the segment register.  I'm still
reeling in amazement at how easy that was.  Wow.

My hat's off to the mingw folks, and I'll be submitting the test
utility (as a new subdirectory for winsup/testsuite) as mingw 
code (under the cygwin license) with an option in the makefile to 
show that it works for MSVC.
