Following is possible with gcc and g++:
#include <math.h>
double sin(double) { return 1; }
int main() { sin(1); return 1; }
Why I don't get any warnings like:
sin prevously defined in math.h ...
when I compile with -Wall -pedantic -ansi.
Why is it possible to overwrite the definition of sin, is this part of the standard?
Secondly the definition (not declaration) of double sin(double) misses a variable! Is this ok, when the variable is not referenced in the code?
Thanks in advance, Florian

I would address your question to the comp.lang.c newsgroup. They are very knowledgable about such things.
