[Pandas-dev] Setuptools detection of host cpuinfo and/or header file availablity

[Stephen Lin]

Well, I can do a runtime cpuid check but there's some expense for that
(not for the check so much, but in making the executable include both
code paths into the same executable and making it possible to select
between them at runtime...). Also, that still leaves the header
availability issue.
