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
