   Thanks. I frequently configure using --with-newlib --without-newlib and
configure gets it right, so I won't just grep the configure args for
--with-newlib. Instead I use AC_SUBST to export with_newlib to the
Makefile.

   So, here is the patch to implement the config.cache file trick: Create a
config.cache file with all the right link test answers for newlib just
before running configure, in both Makefile.tpl and config-ml.in. This allows
sparc-unknown-elf to build libstdc++-v3 with unmodified
libstdc++-v3/configure.ac. Libgfortran's configure.ac needs just the symbol
versioning patch ported from libssp. And that's it!

   The file config-newlib-linktests.cache is just an extract of the
config.cache files I had lying around, except for the last four entries that
I had to extract manually from libgfortran's config.log because they're not
saved to config.cache. It's reasonably straight-forward to add entries as
needed.
