How to use math functions in Cosmic and Raisonance?

I wanted to compare how the most important C compilers for STM8 perform on some standard benchmarks. However, I've run into a problem with Whetstone: I get linker errors for the math functions in the Cosmic and Raisonance compilers. Both provide the math.h header, but apparently there are some extra steps needed that I don't know about.

In Cosmic 4.3.13:
error clnk stm8s208mb.lkf: symbol f_cosf not defined

In Raisonance 2.56.15.0092:
ERROR 100: UNRESOLVED EXTERNAL
