commit 94d42e379702606ec09b241d54ed7ad72cfaff99
Author: Jason Merrill <jason@redhat.com>
Date:   Fri Oct 5 18:59:08 2012 -0400

    	* acinclude.m4 (gcc_cv_gas_version): Try bfd/configure --version first.
    	* configure.ac (gcc_cv_gld_version): Likewise.
    	(gcc_cv_as_aix_ref): Fix typo.
    	* configure: Regenerate.
