hm, i wasnt Cc:-ed to that so i didnt read it yet. I have just followed 
the logical ARHC_SUPPORTS_* idiom which reads more naturally than 
HAVE_ARCH_*. But ... no string feelings, changing it is easy enough, i 
renamed them and pushed out the new iteration to:

   git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-kgdb.git

diffstat and shortlog did not change (just a rename of these config 
variables) - but i'm including them below for completeness of the 
submission.

any other observations?
