Re: (fixed patch) pe-dll fix for exporting common symbols

   I have yet to figure out how bfd is laying out common symbols, and how
   I can access the info to write out the offsets into bss/common section.

The linker lays out common symbols in lang_common in ld/ldlang.c.

I believe the code you are patching is run in the after_open emulation
routine, which is before the linker has laid out common symbols.  By
the time of the before_allocation emulation routine, the linker will
have laid out the common symbols (see lang_process or ldint.texinfo).
Assuming you are not doing a relocateable link, there should be no
more bfd_link_hash_common symbols after that point.
