Jörg,

That would be very helpful. ;-)

For various targets, it is often done in crt0. (Wandering between AVR,
PowerPC, 68k, and NEC v850, I'm comfortable with that, not least because
the -nostartfiles option makes it easy to eliminate stack/bss/data
initialisation in favour of a custom brew.)

To help circumvent the avr muddle, I keep the following reminder:

   avr-gcc:    Still generates do_clear_bss, do_clear_data, exit,
               and stack references, if main() exists. Use
               another function name, if necessary.

That would not be missed, I think.
