Hi, thanks for your reply.
Error handler should not stop at the first error and report the errors as many
as possible.
When there are two errors in code, the second error of undeclared ‘b’ is
static int  f1(void;   //error
static int  f1(void)
  return b;      //error

$gcc -c s.c
s.c:2:13: error: storage class specified for parameter ‘f1’
    2 | static int  f1(void)
      |             ^~
s.c:3:1: error: expected ‘;’, ‘,’ or ‘)’ before ‘{’ token
    3 | {

Maybe it could be improved at some extent.
