Additionally I eliminate the generation of an new import table
for pseudo-relocation version 2, if the _nm_thnk_<name> and _imp_<name>
is already present.

ChangeLog

2009-01-22  Kai Tietz  <kai.tietz@onevision.com>

        * pe-dll.c (tmp_seq2): New static variable.
        (make_singleton_name_imp): New.
        (make_import_fixup_entry): Use for v2 the _imp_<name> symbol and
        avoid duplicate import table generation for same symbol.
        (pe_create_runtime_relocator_reference): Make reference for
        64-bit 8 bytes.

Tested on x86_64-pc-mingw32 and for i686-pc-mingw32
Is this patch ok to apply?

Cheers,
 i.A. Kai Tietz
