red hat 9 != 9.0

[Paul Heinlein]

On Red Hat 9 systems, /etc/redhat-release reads

  Red Hat Linux release 9 (Shrike)

src/misc.c won't parse this correctly because it scans for "%d.%d". I 
guess there are two ways to set the classes:

* just let it be redhat_9
* by fiat, declare it both redhat_9 and redhat_9_0

The patch below, made against 2.0.6, takes the first approach, though
I certainly can understand the arguments for the second. (Warning: I'm
not a C hacker. This looks right to me, and it seems to work as
expected on Linux/gcc boxes, but any fixes are certainly welcome.)
