This is good news. As far as I know R has built for quite some time now on a number of 64 bit platforms (Linux on AMD Opteron/Athlon64, Solaris/Sparc) but I can't recall seeing a build on Intel with the 64 bit extensions. By the way, did you happen to run `make check' just for kicks?

Dear mailing-list members,

In the days of cheap RAM and microarray applications feasting on memory,
64-bit computers become more and more useful - to actually make use of memory
beyond the magic 4GB border. I would like to report the success of running
64-bit R on an Intel Xeon EM64T machine under Linux. Just like on an AMD
Opteron, R v2.0.0 compiles fine (and out of the box) and is happily allocating
memory until RAM and swap reach their limit.

Hardware:
- HP xw6200 workstation
- dual Intel Xeon 3.4GHz with hyper-threading enabled
- 4GB RAM, 4GB swap

System: either
- Fedora Core 2 x86_64 bit Linux
or
- Red Hat Enterprise Linux Workstation 3.0 x86_64 bit

R:
- v2.0.0

Really, no problems at all during setup, a big thank you to the R developers
making this possible!

Best wishes,
Michael
