Building... Should know today but I'm on vacation in Costa Rica.

Testing a fix. I'm 95% certain that _REENTRANT should be defined on
HP-UX 10 even when not linking with -lcma (dce thread library). This
should provide a build environment closer to HP-UX 11 POSIX environment.
We should also always link threaded applications with -lc as libc was
enhanced to add reentrant support in HP-UX 10. -lc_r remained for
HP-UX 9 compatibility.
What is unclear is what happens to the locking needed for some
reentrant routines. I'm thinking it should just work as it does on
HP-UX 11 when not linking with -lpthread ("single" thread). There
is code in libc to do this locking (_p_mutex_lock/_p_mutex_unlock)
but it is hard to tell what it does because it makes a couple of
indirect calls. Couldn't find any documentation on this.
