ideally gcc should not emit _any_ bogus warning. Life is too short to
comb through crappy warnings and to keep in mind which ones are relevant
and which ones are not. compiler-intel.h does not make use of the
annotations for example.

ok - when CONFIG_CC_DEBUG_ALLOW_WARNINGS=y - and then the work flow
would be to go for single-occurance warnings and eliminate them (because
their annotation is moot).
