My work around fixed this problem. I think David's configuration test fails
for this function but it is really there, so when we define the function
there is an error. The workaround was giving the numpy function a different
name, npy_tanhf, then #define tanhf npy_tanhf.  Since all the tanhf
references are replaced before the compilation pass the problem goes away.
Ideally, the presence of tanhf should be detected, so I guess that's where
the official fix should be. All the numpy tests were passing on the
Windows_64 platform.
