Platform specific issues are not covered in vcl - vcl only deals with
gui. Other platform specific issues are abstracted by other things (sal,
osl, vos, etc. - please read the technical overview document at:

It is much better that what I can tell you @ 00.41 from the top of my very
own head.

That is what the copyright assignment part of OO source is designed to
avoid. It is also possible that copyright on a work - or parts of it -
that has a vague set of 100+ contributors in whose case nobody really
knows who did what is unenforcable.

This is a purely political issue. I don't really have much to say on this.

Ummm... You are not assigning over all of your code. You assign copyright
to a specific modification to the OO code. The resulting code (that is -
the original code + your modification) is made available under LGPL 2.1
(which automatically means it is available under GPL). This means that
part is for ever free and available to anybody who wants to use it as

And I get a distinct feeling most people haven't read SISSL and don't
understand what it guarantees about *your* code and it's functionality
should somebody choose to use it under SISSL.
