Argh... OK, going through aranym with debugger has exhonorated it. My
apologies ;-/ It *is* gcc in sid. Testcase:

extern int foo(int);
void *bar(int n)
{
return (void *)foo(n);
}

and gcc -S -O2 turns that into
bar:
link.w %fp,#0
unlk %fp
jra foo

Spot the obvious bug... BTW, why on the Earth does debian-ports m68k tree
use gcc-4.3 with Cthulhu-scaring 700Kb gzipped patch and does *not* have
gcc-4.4?
