Well, I wasn't listening until Jonathan passed this along to me.  I've been
off of tech-net for almost 6 months.

Exactly why would you have to yank any of the support functions from libc?
If a given operation is open coded, they should never be called, so what's
the lossage?  (Remember that I haven't seen the start of this thread, though
I have moved it to tech-toolchain with a Bcc to tech-net.)
