As PE-COFF targets don't have GOT tables and ELF-shared object model, it would
be absolute incorrect to return here result of default_binds_local_p (exp)
instead of true. The function 'default_binds_local_p' is ELF-specific and is
not usable for PE-COFF targets at all.
This testcase contains double declaration of myVar.  You can see this by
turning on -Wall option on compile.  The cause is that in the header the
extern-keyword is missing.
This is no gcc bug.  This is a binutils bug, which doesn't see that here are
two equal named symbols defined - one in data and one in comm.

  I noticed that earlier by a different bug, that .comm double definitions in
.comm aren't detected on link-time.  This is a binutils bug.
