[PATCH] Slightly better way to __USE_MALLOC

[Phil Edwards]

Very nice, gentlemen.  And as an unexpected bonus, this dovetails
nicely (I think, so far) with my plans to unify stl_alloc.h and
stl_pthread_alloc.h/pthread_allocimpl.h.

Two notes:

1)  We should note, if you didn't do so, which versions support this
    technique.  (I think the "extensions howto" is already split up to
    do this, depending on whether this is backported for 3.2.)

2)  Please add some phrase about "the /value/ of the environment variable
    doesn't matter in version <foo>, just as long as it's present in the
    environment."  I could see the value making a difference later.

Again, most excellent work.  (I wish I'd helped.  *grin*)
