Re: true 64-bit FORTRAN compilers for Windows XP 64??

So I installed Windows XP 64. off-topic, but Long sad story, but none
of my PCI cards had drivers for Win64, so had to buy brand new video
card, USB 2.0 card. Plus my expensive HP printers and scanners are
no-go, as HP thinks a 2-yr old $699 printer and $3K scanner is too old
to support anymore ... grrrr.......! No problem, I moved them to my
Linux box.

Now the real hassle:: We have umpty-ump old FORTRAN programs that
would really benefitr from a 64 or at least 48-bit address space.

I try the latest Intel compiler, but the documetation is mighty cagey--
it says it's a 64-bit compiler, but "print *, sizeof( MyPointer )"
still reports "4", not "8". Am I missing some command-line option to
enable true 64-bit code generation?

If that's not possible,
Does anybody know of any REALLY, truly, fully 64-bit FORTRAN
compilers? One that generates true 64-bit code, with 8-byte pointers?


Preferably for Windows XP 64, but Linux could be harnessed in a pinch.

The Intel compiler comes with both 32- and 64-bit versions, both Windows and linux. The 64-bit ones (ia64 and em64t, the latter being what you want) have 8-byte pointers. You can compile with either 32- or 64-bit compiler on either a 32- or 64-bit system. There is no automatic selection, it's up to you. Most alternatives have similar 32/64-bit capability.
