Duplicate Symbol

[Vardhan, Sundara (GE Infra, Energy)]

Hi Ian

I forgot to mention that I had used AIX as and AIX ld when compiling the
gcc on AIX. Perhaps the as does not understand the hidden symbols that
are to be hidden. I plan to give a try with GNU as  and see it matters.
I think using GNU as on AIX causes some issues.
I will try that.

With Regards

Vardhan

It is normal to have both, yes.  The situation on AIX is uncommon.
Normally linking against -lgcc_s and -lgcc is fine, and is done because
there are a few objects which are put in -lgcc but not in -lgcc_s.  I'm
not sure how this is supposed to work on AIX.
