New Revision: 5511

Added:
   mpich2/trunk/confdb/aclocal_config.m4
Modified:
   mpich2/trunk/confdb/aclocal.m4
Log:
Added a PAC macro to allow for sandbox sub-configures. This allows us
to call sub-configures and check if they succeeded or not before
performing some action. AC_CONFIG_SUBDIRS doesn't allow this -- a
sub-configure failing will result in the top-level configure failing
as well.
