I may have misunderstood what merging constants does. If it's only
merging identical constants, then inhibiting it won't help me.
My problem is that the debugger will not break on a definition for a
constant, and in some cases it will not allow me to override a
constant value. It appears that the compiler may be doing some kind
of optimization, though I'm using the -O0 switch.
Are you saying (in your first response) that aliased constants won't
have this problem?
