New Revision: 6642

Modified:
   mpich2/trunk/src/pm/hydra/tools/bind/hwloc/hwloc/config/hwloc.m4
Log:
Bug fix in the check to see if the compiler supports C99. hwloc
requires C99 support, so we force it to fail when the configure
doesn't support it (for example, when we pass the -std=c89 flag) and
disable it.
