The use case for this appears to be for fields that normally have a numerical value, and where particular numerical 
values have no special significance, but where certain numerical values have a special meaning - for example, a field 
that's normally a timeout in milliseconds, but where a value of 0 means "time out immediately" and a value of 
0xFFFFFFFF means "never time out".

Would a more descriptive name for it be something such as BASE_SPECIAL_VALS?
