I sup'ed a new source tree this evening, fixed the bug in vfs_conf.c
(just add #include <sys/fcntl.h>) and rebuilt a kernel to verify that my
dosemu still works.  It does.

I've put updated kernel/libarch/gdb/fdformat source replacements into
ftp://sipb.mit.edu/pub/netbsd/dosemu/netbsd-src-current.950703.tar.gz
with instructions alongside that as README.

I'm off-net for the rest of the week.  If you have problems, hold off
until Saturday.
