Hi All, I got the impression that I got colors in diag output depsite the fact that I got no GCC env var setup. The version I used is CX08$ cc --version cc (Ubuntu 5.4.0-6ubuntu1~16.04.1) 5.4.0 20160609 This is a bit of a problem because I don't use an xterm, and the term I used don't understand vt100 (xterm, etc..) escape sequence. my TERM env var is properly setup, emacs etc all works with my TERM and terminfo database that define how to do colors. Would it be posible that gcc honors the TERM variable setup, if using termcap/terminfo is too complicated, at least disable coloring if TERM is not vt100 compatible. Thanx in advance Cheers, Phi
