Unfortunately, they still suffer from needing both _BSD_SOURCE and
_SYSV_SOURCE defined to compile large classes of programs. Someday I'll
patch this...

This probably will break gdb. A fixed version will be out Real Soon Now
(note: I don't _know_ that gdb is broken, but it definitely accesses
things after u_phys).

This may be true; however, we've been doing this since 2.0 came out with
not a system crash yet. I've tried it several times with 2.0.1 and no
ill effects have been forthcoming (we keep the X shared libraries on
/usr/local/shlib; /usr/local is on a SparcStation 2).
