To All:

I'm using g77-fortran on the PC via Xandros-linux.
On this machine, real is 3 bytes and double precision
is 4 bytes. [For most unix machines, real is 4 bytes
and double precision is 8 bytes.] Is there any "quick
and dirty" way to force 8 bytes computation on the PC?
I.e., something simple like an option for g77,

g77 -64bits -o <executable> <fortran code>

I do NOT want to do a major rewrite on the code
(including porting to C or C++). Also, I already
tried using REAL*8. The machine defaults to 4 bytes.

Any "quick and dirty" solution with other fortran
compiler (g90, etc) would also be okay (as long as I
can use the same code more or less).

Thanks in advanced for your help.
