I'm using a RedHat 6.2 install, upgraded to 2.4 kernel.
[root@aucharn log]# gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
gcc should be okay.

Tried it with no luck.
I'm also trying things with the check commented out, and it looks like
the first error is in the READ_CAPACITY command:

I'll hack around and see what I can find out...
