I'm working on it.  I should have said it's trivial if you have
access to the platforms to be supported.  I've tested a fix
that supports pickle streams generated under Win32 and glibc.
That's using the "native" string representation of a NaN or
Inf.

A perhaps simpler approach would be to define a string
representation for Python to use for NaN and Inf.  Just because
something isn't defined by the C standard doesn't mean it can't
be defined by Python.
