Hi John,

BTDT and forgot about it, because I now always use
sigaction and related functions to handle signals.
(Provides much more control over signal handling)

But to get rid of the warning you can use the
following code :

# include <stdio.h>
# include <signal.h>
void dotrap(int x)
{
}
int main()
{
    void (*f)(int) = dotrap;
    signal(SIGINT, f);
    return 0;
}

Best regards
Johan
