Is there a description for what has to be done in GCC to enable DWARF
with AIX as/ld? E.g. is it required to support the ".dwsect" pseudo?
Is there already a plan from someone to make GCC produce DWARF on
AFAICT, for gcc+gas it should already work with binutils that include
the AdaCore patch for DWARF support. But this has apparently not been
tested with AIX ld, and there are AdaCore local patches pending.

This is probably what we'll end up doing, one way or another. That's
good enough for the goals I'm trying to achieve in the short term
(which means up to 2 years in my case ;-).
