New Revision: 22930

Modified:
   seismo/3D/SPECFEM3D_GLOBE/trunk/flags.guess
Log:
build: Make flags.guess smarter on Cray systems.

The 'ftn' compiler on Cray is really a wrapper around other compilers,
so you need to specify options as if using the underlying compiler.

I tested the compilers available on ARSC and they seemed to work, but I
just made an educated guess as to the correct checks for the Intel and
PathScale compilers.
