[PATCH] mingw64 build.

[Ilya Tocar]

Hi,
Even after your patch
https://sourceware.org/ml/binutils/2013-12/msg00225.html
Mingw64 build is still broken for me with
error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
This patch fixes it.

	* peXXigen.c (rsrc_process_section): Use ptrdiff_t as the type for
	pointer arithmetic.
