Gcc compiled XDD only detects 1 cpu

Question

I recently installed XDD for benchmarking a RAID array, but noticed it only detects one of the four cores on my Q6600.
OS release and version, Linux 2.6.27-ARCH #1 SMP PREEMPT Sun Dec 21 09:13:30 UTC 2008
Machine hardware type, x86_64
Number of processors on this system, 1
Page size in bytes, 4096
Number of physical pages, 1012708
Megabytes of physical memory, 3955
System info:
$ uname -a
Linux superheavy 2.6.27-ARCH #1 SMP PREEMPT Sun Dec 21 09:13:30 UTC 2008 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux
The program is compiled from source with an OS specific makefile provided by the author.  For compilation, I ran
make -f linux.makefile xdd
as suggested in the FAQ.  Is there a way to compile this program so it properly detects all 4 cores on the processor?
Here is the source and the contents of linux.makefile:

Any help or direction offered would be very appreciated.  Thank you.

Answer 1

I have sent an email concerning this problem to the author.  Any advise in the meantime would still be quite helpful.  Once resolved, I will submit an XDD package to the AUR.
