I don't see what -O0 has to do with it.  Really these should
be emitted all the time.  They never actually create data in
the program.

Compare with the following c++ program:

  const int foo = 42;

Note that C++, unline C, defines "foo" to be an integer constant
expression; foo need not appear in any data segment.

Dwarf2, for instance, is able to represent this directly in
the debugging info.  Though I see that there is a bug in that
at the moment...
