[Xastir-Dev] Argh! make problems

[Gerry Creager N5JXS]

I'm *not* inclined to backrev a kernel for a variety of reasons, and 
you've just added to 'em.  Simply, most of my kernel upgrades are 
security-related.  If there's a known vulnerability, and it's reported 
and reported-fixed, I'll rev the kernel.  I'm therefore less likely to 
backrev and leave a known vulnerability in place.
