[SciPy-dev] Undefined NAN in amos_wrappers.c errors on Solaris amd64

Finding that many of the other .c files in scipy/special/cephes 
contained an extern NAN definition, I ended up inserting the following 
in amos_wrappers.c. The file now compiles and 'python setup.py build' 
finishes, but is this the "right" fix? I would have thought there was a 
common header where this should be declared?

extern double INFINITY, NAN;
