Ehh, meet the joys of embargoes.
The code was tested (and people even found subtle arm64 problems due
to that testing), but because it couldn't be made public until today,
it didn't go through all the usual infrastructure we depend on.
But:

it should be fixed now in -git.

Can we call this something informative? Like
int __gcc_4_4_is_garbage_that_shouldnt_be_used;
or something?
That is, if we actually want to really drag out this whole pointless
pain of allowing ancient compilers?
Guys, at some point we need to switch to 4.6. The people who feel the
pain today *will* feel the pain at some point. Just get it over with
already.
