Actually, I just happened to find out recently that gcc 3.3 does have
a -mlongcalls on ppc. This switch seems to clear up an analogous
problem on ARM, so I think waiting for this is the most efficient way
to go, presuming of course that 3.3 won't be too long coming. I
wonder if there is a simple way for me to excise this functionality
from gcc CVS and maintain a patch until 3.3 is released? Sounds
pretty involved.
Take care,
