No. 2.0.2 is a release and it sources won't change. If the fix proves
it's stability in 2.1.1, it will be merged back to 2.0.3 which will be
the base for the next release: 2.0.4.

We used the GNU linker on win32 for years and it worked. We know that it
has it's flaws but it isn't that bad after all.

There are different levels of development code. the linker is really
bleeding edge, most other stuff in 2.1.1 is rather stable.

The internal linker doesn't support all options yet.
