As Hugo already noted...
The value must be within the range of 'int'. Anything else is 
undefined.

Unsigned is of course more natural for bit fields and especially bit 
masks.

For those symbolic constants are better than enumeration members 
anyway:
1) you can use the high order bit (INT_MAX+1),
2) you can use #ifdef.
