enums, pcc & all that

[Root Boy Jim]

	I get tired of seeing
	
	    #define MASK1   0x01
	    #define MASK2   0x02
	    #define MASK3   0x04
	    ...
	    #define MASKN   0x8000000

Me too. That is like a #define ONE 1, #define TWO 2, etc. Why not
#define MASK(x) (1 << (x))	/* or x-1 if you like */
	
	and even the corresponding enum is a pain.

Or define the bit numbers as enums and generate masks from them.
enum bits { ox, ow, or, gx, gw, gr, ux, uw, ur, sticky, sgid, suid };
#define SUID MASK(suid);	/* danger! */

	So, a filter that expands
	
	    enum_mask { MASK1, MASK2, MASK3 ... MASKN } 
	
	into the appropriate series of #defines or enums is useful...
