With functions having this sort of signature, I am guessing that the
library was written in FORTRAN?

G77 for reasons unknown likes to add an underscore to the end of the
names of functions defined in FORTRAN. So in your code, you probably
need to declare and use wssmp_() instead of wssmp(), etc., everywhere.
To avoid the need for the ugly underscore, you can
#define wssmp wssmp_
(etc.) at the top of the file where you declare the functions.
