Yeah, but this affects only those people who use the in-tree build of
the libraries.

The problem for distributors remains the same: They have a strong tendency
of building libraries indepently, with --enable-shared (so that they can
easily apply fixes without rebuilding the world). These distributors on AIX
would notice that the GCC configuration attempts to link with "-lintl"
but not with "-lintl -pthread" and thus the configuration detects that NLS
is not usable.

Arsen: Where in the GCC tree is this part of the GCC configuration? Is it
in some configure.ac owned by GCC, or does it come from gettext.m4 ?
