label 'continue' already bound, unreplaced symbol 'return'

[Pavel Roskin <proski@gnu.org>]

Hello!

Here are some interesting testcases from the same hal.c from ndiswrapper
that was triggering the crash.

static inline int foo(void)
{
    do {
    } while (0);
    return 0;
}
int bar(void);
int bar(void)
{
    return foo();
}
typeof(bar) quux;


hal.c:12:13: warning: symbol 'quux' was not declared. Should it be
static?
hal.c:3:5: warning: label 'continue' already bound
hal.c:3:5: warning: label 'break' already bound


static inline int foo(void)
{
    return 0;
}
typeof(foo) quux;

hal.c:3:5: warning: unreplaced symbol 'return'
hal.c:1:19: warning: unreplaced symbol 'return'
hal.c:5:13: warning: symbol 'quux' was not declared. Should it be
static?


static inline void foo(void)
{
    do {} while (0);
}
typeof(foo) quux;

hal.c:3:5: warning: unreplaced symbol 'break'
hal.c:3:5: warning: unreplaced symbol 'continue'
hal.c:1:20: warning: unreplaced symbol 'return'
hal.c:5:13: warning: symbol 'quux' was not declared. Should it be
static?

"extern" before "typeof" fixes all warnings.
