Microsoft has distributed GPL'd software for years

Microsoft has been distributing GNU GPL'd software in the Interix (now Services for Unix package) -- in particular the gcc compiler.

The download includes GPLv1 and GPLv2 text; some of the tools are licensed "GPLv2 and later". The source code, or where to find it, is not apparent.

Perhaps Microsoft has felt itself above copyright law these past few years already?
