I've got a program that uses sin, cos, pow, and sqrt functions to calculate IIR filter coefficients based on specifications. Although the math.h include file has definitions for these the linker complains:

Severity and Description Path Resource Location Creation Time Id
undefined reference to `cos' Seneca libfilters.c line 664 1185678363046 49100
undefined reference to `pow' Seneca libfilters.c line 664 1185678363046 49101
undefined reference to `sin' Seneca libfilters.c line 664 1185678363046 49099
undefined reference to `sqrt' Seneca libfilters.c line 459 1185678363046 49098
Can anyone verify if these functions are supposed to be available for the AVR32UC3A?
In a related note, is the source for the C library available, stuff like floating point operations on the AVR32? I found those very helpful when I was doing ADSP2189 development.
