Hi,

I just wanted to update my amd64 workstation to an up-to-date current,
but i just hit a compilation problem for libpthread_dbg (same error
with cross-compilation from i386) :

dependall ===> lib/libpthread_dbg
#   compile  libpthread_dbg/pthread_dbg.ln
CC=/local/src/NetBSD/tool/amd64/bin/x86_64--netbsd-gcc /local/src/NetBSD/tool/amd64/bin/x86_64--netbsd-lint -chapbxzF -d /local/src/NetBSD/dest/amd64/usr/include  -I/local/src/NetBSD/src/lib/libpthread_dbg/../libpthread/arch/x86_64 -I/local/src/NetBSD/src/lib/libpthread_dbg/../libpthread -I/local/src/NetBSD/src/lib/libpthread_dbg    -i /local/src/NetBSD/src/lib/libpthread_dbg/pthread_dbg.c

*** Failed target:  pthread_dbg.ln

The problem seems that `fxsave64' definition is protected with `#ifdef
_KERNEL' in `machine/mcontext.h', which leads to a sero sized struct
in `machine/reg.h'.

Thanks in advance,
Regards.
