have you stripped them? debugging info tends to get huge. Also you might
want to compilöe them without exsception tables (-fno-exception).

Also maybe libbfd &c. was linked statically into the executables.

Then, with a 99.9% chance, the settings were different ;)

How many differences are there ("cmp -l file1 file2 | wc" will outpout a
measure for that).? If there are few only then maybe its an embedded date.
If the binaries are almost identical (<10 differences or so) then cache
colouring effects might take place.

Improbable, however, if the only thing you changed were binutils I guess
that was it. Can you try with the old binutils?
