Just a little bit more:

You should be able to fix this by either deleting the line that
says 'extern int isnan(double);' or replacing it with #include of
math.h. It looks like the code is written for a very old unix system
that didn't declare these functions in its header files; you probably
don't need that any more on modern systems.
