>Description:
GCC refuses to compile a declaration that follows immediately after a 'case' in a 'switch', even in C99 mode:

int main()
	{
	int x = 1;
	switch (x) { case 1: int y = 7; }
	return 0;
	}

Says GCC: In function `main': parse error before "int".

However, if I add a dummy statement before the declaration, GCC compiles it fine:

int main()
	{
	int x = 1;
	switch (x) { case 1: 4 + 5; int y = 7; }
	return 0;
	}
