Unfortunately the little monster is statically linked.
(text + data over 4MB...) Anyway this is what i did,
#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
#include <signal.h>
int main(int argc, char **argv) {
if (argc < 1)
exit(2);
signal(SIGFPE, SIG_IGN);
execvp(argv[1], argv+1);
exit(1);
}
and exec netscape.bin thru it.
