Re: g++ 3.2.x build problem

Hi David,

Thanks for your quick response, and sorry for my delay -- I was out of
office since then.
Regarding what you asked:
1) AIX version is 5.1.0.0, and it was determined correctly, as you can see
in the paths in the error messages (that is, in my original message).
2) I honestly got no idea why the configuration procedure decided not to
default to absense of symbol versioning, as it should on AIX. Will try what
you suggested: --enable-symvers=no (in fact, I'm running this experiment
right now, hope to have the results by tonight).
3) Utilities I use (ld, as, etc) are from GNU BinUtils package, version 2.13
(which is the last stable release, as I can see on gnu.org). Do you think I
should use something else?

Thanks,
Val.
