Looks like this is essentially equivalent to the patch from Fabian Groffen that I recently committed: http://git.savannah.gnu.org/gitweb/?p=libtool.git;a=commitdiff;h=eee4f853019cc246b1d65054771f85ef500098ff The distinction is that you match only x86_64-*-solaris2.1[[0-9]]*, while Fabian's patch matches x86_64-*-solaris*. Is there a need for the more-complex pattern? If so, I can make an amended commit. Fabian's version looks fine to me.

Support 64-bit default GCC on Solaris/x86
In version 4.7, GCC will gain a 64-bit default Solaris/x86
configuration, similar to the existing sparcv9-sun-solaris2
configurations. In order for that to work with GNU ld (Sun ld works out
of the box), I had to make the following minor patch to libtool.m4.
This patch has been tested with a slightly earlier version already
included in the gcc repository for Go support. There's an effort
underway to upgrade the libtool in gcc to 2.4.2. A gcc bootstrap with
64-bit gld and this patch included completed without regressions.
If the patch is accepted, it would be good if it could be included in
libtool 2.4.3 so by the time gcc 4.7 is released, a corresponding
version of libtool is available.
Thanks.
Rainer

Summary could be found in this thread http://lists.gnu.org/archive/html/libtool/2011-10/msg00017.html Note Eric's patch is for *kfreebsd* and *linux* and does not cover solaris. My question is what is result of libtool regression test if instead to add x86_64-*-... you replace $host by $build one line above ? Roumen
