Comment:

 To my knowledge, M_PI is not part of ANSI C, but is part of POSIX. Some
 compilers disable POSIX compatibility by default. The compiler
 configurations that we distribute e.g. with the Simulation Factory
 <http://simfactory.org/> should contain these settings. These may also be
 good examples for which settings your compiler requires.

 I am not going to modify wavetoy-loopcontrol.c since there is nothing one
 can do in the source code (except not using M_PI); rather, the compiler
 options need to be changed.
