INT64

Subject: INT64

Hi,

From the libs I use I find more and more *INT64 version for my platform
(Opteron, Linux, g++).

I guess this is due to a compiler-flag to use 64 bit integers.

Has anyone experience with this. Does this make numerical code
significant faster (due to alignment) or is this just to overcome
2/4 GB of address space?

Can I link "normal" and INT64 libsts the same time or do I have to
compile everything with INT64?

What is the option?

Thanks a lot,

Fabian
