Re: pthreads issue when compiling 7.4.8 on AIX 5.3 -- RESOLVED

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I spoke with our IBM sales reps about this and they suggested we upgrade
GCC to 3.3.3 or later. Their PMR for this is PMR25534,077,649 if you
happen to need the reference. We upgraded to 4.0.1 and got it to compile.

We're now seeing the same socket bug as everyone else. Chris Browne
filed a bug report with IBM and has opened PMR29657,500. We hope to see
resolution shortly.
