Again, works for me.

http://home.tiscalinet.ch/t_wolf/tw/c/c9x_changes.html (search for
__func__) would seem to imply that you are correct, though. Perhaphs
someone more knowledgable about gcc could shed some light?

mulix@tea:~/tmp$ cat foo.c
#include <stdio.h>

#if DEF_FUNC
#ifndef __func__
#define __func__ __FUNCTION__
#endif /* !defined __func__ */
#endif /* DEF_FUNC */

int main()
{
        printf("%s\n", __func__);
        return 0;
}
mulix@tea:~/tmp$ gcc3 -v
