Dunno about PE-COFF, but at least in ELF merging of .data (or .rodata) and
common symbols works by keeping the non-common symbol and it is the behavior
that GCC expects with -fcommon. If the PE-COFF linker handles it the same, then
if you can't use default_binds_local_p, you should at least copy over the
common symbol handling from it.
int i = 5;
in one file and
int i;
in another one with -fcommon just provides the int i = 5; definition and
int i; in two files provides int i = 0; definition.
