the network stack has a few bits that don't work without
changes, as i painfully learned with 9vx.

if a patch to the c compiler showed up that did this and
were distributed with sources, i would only consider using
it only if there were an automatic way of locating code that
might change behavior with a lowish false positive rate and
a verifiably zero false negative rate.  even then it would be
very painful as i would need to verify that the system and
all our shipping code works properly with new rules.  i see
little upside.

in short, That Boat Has Sailed.
