that's my question. I've Gcc 4.4.1 and that function isn’t present, i had installed the 4.3 and 4.5 versions with the same result :-/

I know that this function is not the C-ANSI standard, but I didn't write the code and I need compile it in my distro. A friend of mine had the same version of the compiler in Fedora, and Gcc compiles with no problem (using stdio.h and stdlib.h).

So if someone can tell me if the function is/isn't available in my compiler.. I'd be thankful.

Greetings.

btw: this my gcc version:
