Build V2.
Yep. Someone (you?) contacted me a while back claiming that
if I
would just pass the right flag to the linker, I could get
AIX to
behave like any other Unix platform and I wouldn't need
these special
shenanigans. He promised me a patch, but, well, I never got
it.
Unfortunately, these messages seem to have disappeared from
my
electronic record :(

Yeah, nasty. Volodya, is there a way to embed a comma in a
feature
value?
