Done in r3512. Hurray for inclusion instead of code duplication. (I 
originally copied that stuff from numarray, which inspired numpy's 
design of that stuff, but since back then would couldn't depend on 
either...)

Also in r3512, I inserted the definition of isfinite, copied from 
numpy's umathmodule.c.src at the top of _transforms.cpp. If it works for 
numpy, it should work for us.

I'm slightly worried that this stuff will break on MSVC... Does anyone 
have the ability to test this svn revision sooner than later?
