I just tried this:

	pair<cpu_it, cpu_it> foundApicId = equal_range( apicIds.begin(), 
apicIds.end(),
		apicId, []( cpu_apic_id const &idRange, unsigned apicId ) { return 
idRange.apicId == apicId; } );

It should be possible that the key for the range has a different type
than than the elemnens in the range so that I can compare against a
part of the range-objects like in the above code.

Instead I'd hat to write:

	pair<cpu_it, cpu_it> foundApicId = equal_range( apicIds.begin(), 
apicIds.end(),
		cpu_apic_id( -1, apicId ), []( cpu_apic_id const &idRange, cpu_apic_id 
const &id ) { return idRange.apicId == id.apicId; } );
