I would argue that this is gcc's responsibility. If a const structure 
variable contains *any* code or data addresses, it's not safe to put it 
in .rdata (or .rodata, whatever the platform calls it), because of 
relocation issues.

So rather than detect a "DLL import", I'd say *any* function addresses 
in a const initializer should cause the variable to go into a regular 
.data section, without any complicated decision-making by binutils.

(Note: this is not the same problem that Danny talks about in that 
message - that usage was legitimate, and there was no attempt to have a 
const initialized variable with a data address.)
