  I just tested the new binutils:

  the linker still writes garbage (or leaves what is on disk before)
when linking executables :(

  The reason is that when I compile Free Pascal Compiler
we use a Cycle strategy, which simply consists of
compiling the compiler with an old version
use the new version to regenerate a second compiler
and so on.

  Normally this process should lead to equal binaries after at most three
steps.

  With ld version 2.7 it works correctly
but ld 2.9.1 as well as ld 2.10 lead to programs that are functionnally
equal but still have unused area with different bit pattern.

  As my file compare is a raw   cmp oldexe newexe
my cycle test fails.

  I read something about this issue in binutils list:
Patch to eliminate garbage in DJGPP execs

  But I did not understand the current stand point
(and I hoped that this problem was fixed in the DJGPP version by a local
patch)
