Does "piecemeal" really mean "in executable code"?

I think so, from the dlltest2.zip, dllimport.c:

If you're initializing a static variable, that's probably not done in executable code.

The difference may be that the compiler can generate the appropriate machine code to calculate the address of fff, but can't generate the right object-file indications to the linker and run-time loader to get *them* to do it - and if the variable being initialized is const, that might not work as it might be mapped read-only.
