I think that the switch name
-fkeep-static-consts might be more consistenly named if it
was given the opposite sense and named something like
-fdelete-unused-static-consts.  The idea here is that by
asserting the switch a particular optimization is _enabled_.
Thus the optimizations performed at each level can be consistently
enumerated by asserting a particular set of switches which enable
specific optimizations.  This would change the present user interface,
however, I doubt that anyone is making extensive use of the current
interface because at present only -fno-keep-static-consts, asserted
at -O0 (no optimization), actually changes the default behavior of
the compiler.
