System: NetBSD snark.cb.piermont.com 4.99.28 NetBSD 4.99.28 (ZWEI) #0: Sun Aug 12 13:52:43 EDT 2007 perry@snark.piermont.com:/usr/src/sys/arch/amd64/compile/ZWEI amd64
Architecture: x86_64
Machine: amd64
>Description:

The following is fine c99 and compiles and runs just fine, but results
in a syntax error if you use it with lint -S:

--------------------
#include <stdio.h>

int main(int argc, char **argv)
{
    for (int i = 0; i < 10; i++)
        printf("i = %d\n", i);
}
--------------------

This turns out to be a serious problem if you want to use c99isms in
portions of the tree that get linted, like libraries.

>How-To-Repeat:

$ lint -chapbxzFS lintest.c
lintest.c:
lintest.c(5): syntax error 'int' [249]
lintest.c(5): i undefined [99]
[etc, etc.]
