binutils-gdb/bfd/ChangeLog
Nick Clifton 32ae0d80cd PE32+ binaries that use addresses > 1^32 have a problem in that the linker 
converts some address expressions into absolute values, but the PE format
only stores absolutes as 32-bits.  This is a partial solution which attempts
to convert such absolute values back to section relative ones instead.  It
fails for symbols like __image_base and ImageBase__, but it is unclear as to
whether these values are ever actually used by applications.

	PR ld/16821
	* peXXigen.c (abs_finder): New function.
	(_bfd_XXi_swap_sym_out): For absolute symbols with values larger
	than 1^32 try to convert them into section relative values
	instead.
