While you're looking at config/ompi_config_subdir* anyway, you may be
interested to know that it mistreats some arguments with special
characters in it. That may not be so important to OpenMPI, but when
passing the same config.cache file down to the sub-configure (which
OpenMPI does not do), then it can be:

It may even be that this comment from configure.ac:
# AC_CONFIG_SUBDIRS appears to be broken for non-gcc compilers (i.e.,
# passing precious variables down to the sub-configure).
hints at the very problem linked to above, but frankly, I don't know
that. Again, if that was a different issue with AC_CONFIG_SUBDIRS,
it'd be great to hear about it.
I don't remember what the issue was -- Jeff, do you remember?
I think we disabled config.cache for other reasons -- namely that we
(Open MPI) internally add compiler flags, so that made config.cache
really difficult to do right.
