library/ops.m
library/nc_builtin.nl
library/sp_builtin.nl
compiler/mercury_to_mercury.m	<--- this is the one you probably missed.

The unfortunate reason why it is in several places is this:
	- NU-Prolog, Mercury, and SICStus all defined different sets of

	- when writing out the `int' file, we need to quote anything
	  that _any_ of the above three consider an operator.
