Hi
I am working on a project where I use the constant M_TWOPI defined in math.h. Despite an #import <math.h> statement at the beginning of my source, gcc flags M_TWOPI as unknown. Strange enough, other stuff from math e. g. trigonometric functions are there. I feel I have a mess with all these imports. Is there a cross reference tool available that analyzes a project and tells one which term is defined where and where it is used. I should add that I am writing my eCOS-app using Eclipse 3.3.2/CDT 4.03. Thanks for help.
   Robert
