2004-12-02 Richard Sandiford <rsandifo@redhat.com>
* configure.in: Include config/gcc-version.m4. Use TL_AC_GCC_VERSION
to set gcc_version_trigger. Remove some now-redundant AC_SUBSTs.
* configure: Regenerate.
2004-11-26 John David Anglin <dave.anglin@nrc-cnrc.gc.ca>
* configure.in (hppa*-*-linux*): Don't add libgcj to noconfigdirs.
