Hello again,

on the workstation were I did the development, the used gcc is 3.3.5
and ld is 2.15. The remarkable thing is that 

    1) 'ld-2.15 --help' and 'gcc-4.0 -Wl,--help' use STDOUT.

    2) 'gcc-3.3 --help' and 'gcc-3.4 -Wl,--help' use STDERR.

Thus older versions of GCC (presumably 3.*) implement a redirection of output.
