[FLASH-BUGS] Flash - Fortran90 compiler compatibility on Tru64

[Mike Zingale]

Colin, we are aware of the issues with the Compaq Fortran 90 compiler, and
hope to have a workaround implemented in the code in the next version of
FLASH.  What version of the Compaq compiler are you using?  Can you try
your problems out on a different platform, without the changes you made?
