Re: [PATCH] PR 68192 Export AIX TLS symbols

[David Edelsohn <dje.gcc@gmail.com>]

Hi, Richi

You mentioned GCC 5.3 release around the time of stage 1 ending in the
GCC 5 status report:

https://gcc.gnu.org/ml/gcc/2015-07/msg00197.html

If the timeframe is later, we have more time to address the AIX libtool problem.

Thanks, David
