New Revision: 3884

Modified:
   MOAB/trunk/config/compiler.m4
Log:
o Use default compiler list provided by autoconf
   - fixes MAC configure issue
   - typically results in selection of g++ over vendor compiler 
       (e.g. xlC) when both are available.  Use CXX= and CC= to
       force vendor compiler if necessary
o When compiler is mpicxx, autoconf sometimes fails to identify
   it as g++.  Add our own checks for g++.
