I don't have Win2k, but FWIW I can't build Emacs with this patch on Windows NT
4+SP5 running under VMware 3.1.1. I reverted Laurynas's DS alias patches,
re-enabled Unixy sbrk in src/msdos.c in the Emacs directory, recompiled libc
and then ran 'make install' in the Emacs directory. I got a segfault, when
temacs was trying to dump.

So it seems to me that we need a fix for the DS alias problem, for an Emacs
build with Unixy sbrk to work under Windows NT 4.

Currently the easiest way to get the Emacs build to work under Windows NT 4 is
to disable Unixy sbrk in src/msdos.c.

Bye, Rich =]
