Okay - these grep results look a lot like our system and the compile
looks good.  Our system version is

bonito<141>$ uname -a
SunOS bonito 5.8 Generic_108528-14 sun4u sparc SUNW,Ultra-2

The compiler we use is Sun's:

bonito<145>$ /opt/SW6.2/SUNWspro/bin/f77 -V       
f77: Sun WorkShop 6 update 2 FORTRAN 77 5.3 2001/05/15

but the large file support has worked for a long time on Solaris.  I
vaguely remember that there is a parameter that may still need to be
set to permit a filesystem or a disk volume to permit files > 2 Gbyte.
But I asked our Solaris expert and he does not remember this so I
could be wrong.

To check - I just wrote a task to creata file and then expand it by
sizes I gave it and this program ran well over 2 Gbytes on bonito with
no problem.
