This is the test code I came up with. To the best of my
knowledge, every ANSI C compiler should be able to compile it, but
not without warnings:
----------------------- warn.c -------------------
#include <stdio.h>
main(const i, const int * const p)
{
char *c;
switch (*p = p = *c)
{
case 0:
printf("%p", c, p);
}
*c = &i;
c = p;
while (1 || (unsigned int)3 >= 0 ||
((int)-1) == ((unsigned int)1));
return;
}
--------------------------------------------------
It's meant to provoke a number of non-fatal warnings that would
cause compilation to fail with -Werror or a similar option in
other compilers. It's very important that it doesn't fail without
such an option. So I ask everybody to review it and/or try to
compile it with
$ cc warn.c
If it doesn't compile with any *C* compiler, please report back.
I'm fully aware that it won't compile on *C++* compilers.
