Yes.  What you'd really use is a macro.  Maybe something like:

#define bcf(var, bit) var &= ~(1<<(bit))

And then in your C program you can say obvious stuff like:
	bcf(var, 5);
Then you'd sit there and hope that the compiler writers included
some special case optimization to reduce that back to the single
instruction it should be, since that's probably NOT a case that
generic C optimizers would catch.
