Re: [toolbox-l] RE: Compile errors from GCC tools for AIX (aix43-000718)

The version of gcc that is currently out there is "beta" and will soon be 
superceded by another version that was developed for the GNUPro Tools from 
Cygnus.   My understanding is that Cygnus' versions do not map precisely to
the "standard" versions.  I'll try to get a direct response from Cygnus
on how to answer the question.  It is "later" than 2.95.2 from my
understanding.  Hopefully all of this will settle down at the 3.0 merge as
the AIX fixes get pulled into the main branches.  I believe that this level
does contain a number of fixes for AIX which are not in the standard GCC release.

Those pthread.h errors are fixed already in the AIX 4.3.3 service stream and
in AIX 5.1.

What's szbuf?  That just looks like a warning - shouldn't have stopped anything
from compiling.  In AIX, the format argument to printf is const char* - 
szbuf doesn't smell like a const.  I would expect a warning in that 
circumstance.
