>Description:
lint(1) generate a wrong 'syntax error' message when a variable declaration,
from a previous typedef,  is used after a statement (C9X mode).

njoly@petaure [~]> cat sample.c 
typedef int int_t;
int main() {
  int i = 0; i+= 1;
  int_t j = 0; j += 1;
  return 0; }
njoly@petaure [~]> lint -Sw sample.c 
sample.c:
sample.c(4): syntax error 'j' [249]
sample.c(4): j undefined [99]

The problem goes away if using some basic type (int) for j.
>How-To-Repeat:
Run lint on previous testcase.
