Sorry if this has already been reported...

Lint on an AT&T 3b2 running SysV r3.0 behaves inconsistently
on this program:

=========================
void a()
{
        printf("a\n");
}

void b()
{
        printf("b\n");
}

main()
{
        void (*emit)();
        int i = 1;

        if (i) emit = a; else emit = b;  /* lint buys this */

        emit = i ? a : b;  /* lint rejects this */

        (*emit)();
        return(0);
}
==========================

Evidently lint does not like the combination of the void type and
the ?: operator.  Lint works fine if I declare everything "int"
instead of "void".  Anyone have a fix?
