Stuff like libc's namespace.h, or atomic_op_namespace.h, which does
namespacing tricks like `#define atomic_cas_uint _atomic_cas_uint',
has to go at the top of each .c file. If it goes in the middle, it
might be too late to affect the declarations, and result in compile
errors.
I tripped over this by including <sys/atomic.h> in mips
<machine/lock.h>.
(Maybe we should create a new pthread_namespace.h file for the
purpose, but this'll do for now.)
Builds a libpthread that can be dropped into a NetBSD 2/3/4 chroot.
This makes threading work in the chroot when using a NetBSD 5 kernel, no
other modifications required.
