Pade fails to compile on Ubuntu 15.04

[ryanlevy]

There is an error when compiling Pade on ubuntu and I'm not entirely sure how to solve it: error: ‘void*’ is not a pointer-to-object type This error is given for math functions tan,log,exp (see lines 52,60, and 89 respectively). These functions have conflicts with the <tgmath.h> header. Removing said header allows it to compile, but I'm not sure why it was included in the first place.

thanks, I think this works. On some better compilers copysign is a thing... but seems not on my old ones
