Description:
------------
The packages can't compile on newer gcc because you can't 
have an label inside a switch without any statements.

Line 202-204:

default:
/* Do nothing with other types */
}


To fix this we can just insert a ; to make an empty 
statement.

default:
; // fix for gcc 4.3+
/* Do nothing with other types */
}


I'm not sure that it is gcc 4.3. I'm using gcc 4.4.1.

Reproduce code:
---------------
phpize
./configure
make

Expected result:
----------------
The make command will run without any errors.

Actual result:
--------------
oggvorbis.c: In function ?php_oggvorbis_init_writestream?:
oggvorbis.c:202: error: label at end of compound statement
