[lwip-devel] [patch #5822] Handle unused arguments

[Simon Goldschmidt]

Follow-up Comment #10, patch #5822 (project lwip):

I've converted all statements like '(void)arg;' into 'LWIP_UNUSED_ARG(arg);'

Does somebody know how to get gcc to generate a warning for statments like
'if(arg);' or 'arg = arg;'??? That would simplify getting all the points
where LWIP_UNUSED_ARG() should be used.
