Sorry, no, as I wrote in my original bug report, I didn't
think it would break anything in the Microsoft builds.
I am not an expert on MS-Windows.

Thanks, but unfortunately that fix broke things for POSIXish hosts that
lack _setjmp.  I tried to fix the problem in a different way,
by editing nt/config.nt, in trunk bzr 110037.  Since I don't
know what the problem was in the MS-Windows build,
it's possible that the Microsoft side still has problems,
but I expect that any problems should be minor and fixable
by further edits to nt/config.nt or similar files.
