bug#18099: AIX TLS symbols do not make it into dynamic libraries

we encountered some problems when building an OpenMP application/library package
because of a missing symbol on AIX 6.1 TL8 running on an IBM Power6 system.

We traced the problem down to an omission in libtool: since the matching string
for AIX


does not include global TLS symbols (letter L of AIX nm) we faced a problem with
a symbol compiled into an object and visible in the static version of the
library being invisible in the shared library object.

In short: could someone add L to above symcode assignment (line 3748 in

Also when reading the AIX nm manual page[1] I see that letter A for global
absolute symbols is equally unrecognized. So it might make sense to add that as
well but have no test case for that.

Regards, Thomas

through r", I found it at
