g77 may be recompiled for large files.

We use: -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE

This allows:

Formatted/Sequential   > 4 Gb
Unformatted/Sequential < 4 Gb
Unformatted/Direct     < 4 Gb

Not quite limitless, but is gains from
the 2 Gb limit.


The CURRENT Intel compiler - 5.0.1 has a
2 Gb limit.  The next release to come out
at the end of this month (6.0) will have
the limit removed.

Regards,
joe
