Hi, > GCC's g++ includes the C <math.h>, #undef's the macros, does a "using > ::sin" > >from the global namespace, and adds inline versions of sin(float) and > sin(long double). thanks for the fast reply. My problem was not to understand what gcc does. gcc works like you described it above. My problem is whether gcc does it correctly according to the ISO standard. In paragraph 4 of section 17.4.1.2 in that standard it says that there should be no ::sin if you include cmath, only a std::sin. But since I am not well trained in legal speak and have only a '98 draft version of the standard available I am not sure if a am right or wrong. Jens -- Lust, ein paar Euro nebenbei zu verdienen?
