BTW, you can get extra warnings by building with the W=[123] option to the Makefile (e.g., 'make W=1').
$ make help [...] make W=n [targets] Enable extra gcc checks, n=1,2,3 where 1: warnings which may be relevant and do not occur too often 2: warnings which occur quite often but may still be relevant 3: more obscure warnings, can most likely be ignored Multiple levels can be combined with W=12 or W=123
