Looks like it. (cfsNN is our Linux cluster where I do self-compiles.)

[fluet@lennon fluet]$ gcc -v
Reading specs from /usr/lib/gcc-lib/i586-mandrake-linux/2.95.3/specs
gcc version 2.95.3 19991030 (prerelease)
[fluet@cfs18 ~ 1]% gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)

Correct.  I was just following up on Henry's observations.
