I noticed that we have a --with-specs option in gcc/configure.ac, added in revision 155208 with this e-mail message: http://gcc.gnu.org/ml/gcc-patches/2009-12/msg00132.html
Nathan forgot to commit the ChangeLog entry, so I have committed this patch to ChangeLog-2009. (Patches to ChangeLog files do not themselves require ChangeLog entries.) More seriously, this option is not documented in gcc/doc/install.texi, as pointed out by Gerald in http://gcc.gnu.org/ml/gcc-patches/2009-12/msg00947.html . We've had discussions circling around this idea in the past, and I was surprised to discover that it has already been committed. Nathan, would you be willing to write some docs for it? Thanks. Ian
