[MITgcm-support] Intel Fortran 8.1: -assume byterecl

[Jason Goodman]

I'm building MITGCM with Intel Fortran 8.1, and ran into a problem 
trying to run the verification tests:

(PID.TID 0000.0001)  MDSREADFIELD: opening global file: topog.box
forrtl: severe (36): attempt to access non-existent record, unit 9, 
file /home/goodmanj/mitgcm/verification/exp1/input/topog.box

It turns out that Intel Fortran 8.1 assumes that in an 
OPEN(RECL=length) statement, the record length is in units of 4 bytes, 
instead of 1 byte as assumed by Intel v7, gcc, Portland, and other 
compilers.  To fix this, I added

-assume byterecl

to the FFLAGS line of the MITGCM build options file.
