>Description:
The following code used to work with older gcc versions, doesn't work with almost-3.3 anymore:

static unsigned char test[1024];
int main(int argc, char **argv)
{
        __asm__ __volatile__ ("
                        call test");
}

Changing it into either

static unsigned char test[1024];
int main(int argc, char **argv)
{
        __asm__ __volatile__ (" \
                        call test");
}

or

static unsigned char test[1024];
int main(int argc, char **argv)
{
        __asm__ __volatile__ ("call test");
}

Works.

Intentional change, or bug?
>How-To-Repeat:
Try to compile the code above.

Results with gcc 3.3:

test.c:4:31: missing terminating " character
test.c: In function `main':
test.c:5: error: syntax error before "call"
test.c:5:34: missing terminating " character
