		 fixes that problem; see PR 2953.

		 However, Ian wrote the following, regarding removing the line
		 below, which explains why it is still enabled:  --djm

		 If you put a patch like that into BFD you need to check all
		 the COFF linkers.  I am fairly certain that patch will break
		 coff-i386 (e.g., SCO); see coff_i386_reloc in coff-i386.c
		 where I worked around the problem in a different way.  There
		 may very well be a reason that the code works as it does.

		 Hmmm.  The first obvious point is that bfd_perform_relocation
		 should not have any tests that depend upon the flavour.  It's
		 seem like entirely the wrong place for such a thing.  The
		 second obvious point is that the current code ignores the
		 reloc addend when producing relocatable output for COFF.
		 That's peculiar.  In fact, I really have no idea what the
		 point of the line you want to remove is.

		 A typical COFF reloc subtracts the old value of the symbol
		 and adds in the new value to the location in the object file
		 (if it's a pc relative reloc it adds the difference between
		 the symbol value and the location).  When relocating we need
		 to preserve that property.

		 BFD handles this by setting the addend to the negative of the
		 old value of the symbol.  Unfortunately it handles common
		 symbols in a non-standard way (it doesn't subtract the old
		 value) but that's a different story (we can't change it
		 without losing backward compatibility with old object files)
		 (coff-i386 does subtract the old value, to be compatible with
		 existing coff-i386 targets, like SCO).

		 So everything works fine when not producing relocatable
		 output.  When we are producing relocatable output, logically
		 we should do exactly what we do when not producing
		 relocatable output.  Therefore, your patch is correct.  In
		 fact, it should probably always just set reloc_entry->addend
		 to 0 for all cases, since it is, in fact, going to add the
		 value into the object file.  This won't hurt the COFF code,
		 which doesn't use the addend; I'm not sure what it will do
		 to other formats (the thing to check for would be whether
		 any formats both use the addend and set partial_inplace).

		 When I wanted to make coff-i386 produce relocatable output,
		 I ran into the problem that you are running into: I wanted
		 to remove that line.  Rather than risk it, I made the
		 coff-i386 relocs use a special function; it's coff_i386_reloc
		 in coff-i386.c.  The function specifically adds the addend
		 field into the object file, knowing that bfd_perform_relocation
		 is not going to.  If you remove that line, then coff-i386.c
		 will wind up adding the addend field in twice.  It's trivial
		 to fix; it just needs to be done.

		 The problem with removing the line is just that it may break
		 some working code.  With BFD it's hard to be sure of anything.
		 The right way to deal with this is simply to build and test at
		 least all the supported COFF targets.  It should be
		 straightforward if time and disk space consuming.  For each
		 target:
		   1) build the linker
		   2) generate some executable, and link it using -r (I would
		      probably use paranoia.o and link against newlib/libc.a,
		      which for all the supported targets would be available in
		      /usr/cygnus/progressive/H-host/target/lib/libc.a).
		   3) make the change to reloc.c
		   4) rebuild the linker
		   5) repeat step 2
		   6) if the resulting object files are the same, you have at
		      least made it no worse
		   7) if they are different you have to figure out which
		      version is right.  */
