I've just checked Sun as and it works the same way (ie.
.weak foo
.weak bar
.word foo
will result in WEAK UNDEF foo and bar symbols).
On the other side, linker if it finds both WEAK and non-WEAK UNDEF symbol of
the same name merges them into non-WEAK UNDEF, so changing it in as should
not cause problems.
