New Revision: 5451

Modified:
   mpich2/trunk/confdb/aclocal_cc.m4
Log:
Added a noopt flag to --enable-strict to allow for all flags, except
-O2 to be used. This allows us to use --enable-strict=noopt and
--enable-g together without worrying about instruction reordering in
gdb/ddd.

Reviewed by goodell.
