A bit off topic, but it reminded me nonetheless.  Anyone trying to build a new 
version of procpcs (>3.4.2) under mips64 will likely need this patch.

Unsure what the reasoning behind this bit was in procps, but it assumes that 
n32 is usable on a mips64 system (atleast, my understanding of the conditional 
is that), and thus defines KLONG to long long on mips64, which breaks 'ps' on 
these systems (you get a nice sigsev).

Thought it'd be useful to pass along.
