Nope, tried deleting and recompiling from scratch, still getting the
exact same problem...
Even tried removing the optimization "-Os" that Frank suggested, but
with no luck...

Anybody has an idea?  I'm sure I could dig in the makefile and tweak
it, but I won't have much more time to spend on a Mac, as I'm leaving
my parents house in a couple hours.  Is there any files you guys would
need to analyse this problem while I'm away from the mac, and try it
again next sunday (or the next one after)?  like config.log or
anything else?

Thanks,
  Simon
