Hi Guys,

  Would anyone care to comment on the patch below ?  It is a nasty hack
  which fixes a problem encountered when using objcopy to convert from
  a PE format image file into SRECs.  The PE format uses the LMA field
  as a virtual size rather a physical address, which confuses BFD when
  it comes to try to generate SRECs.

  The fix attempts to detect when an input BFD is a PE format image
  file (and the output format is not) so that the VMA address of the
  input section can be used instead of the LMA address.  The
  determination of whether the input or output BFD is in PE format is
  based on the name of the format.  If it contains the substring
  "pei-" it is assumed to be a PE image.  Gross I know, but I am not
  sure of a better way to do it.

Cheers
	Nick

	* objcopy.c (setup_section): Use the VMA as the LMA of
	sections that have come from a PEI format input BFD and which
	are not going to a PEI format output BFD.
