Q: Standard C doesn't do fixed point math, per se... what do I need to look for in the compiler software to be able to use fixed point math?

Q: Who has a good math library with trig functions?

A: ARM.  The ARM assembler includes floating point and trig functions.  See: http://infocenter.arm.com/help/topic/com.arm.doc.dui0041c/DUI0041C.pdf.\ and see: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0041c/ch11s03s07.html.
