Besides crake (x-version), fulmar (icc) and lorikeet (cygwin), I hope
the rest of the known failures should pass on the next cycle; the
mac/ppc failures are because we redefine "bool" in a way that broke the
upstream code's c99 assumptions, and the rest are numerical instability
in ts_rank.

IA64 is working fine as far as I can see (specifically, anole is
passing); it's ICC on x86_64 that broke (fulmar).
