On 2010-01-27, an email [1] was sent to the mailing list by Wolfgang Denk which clarified the intended licensing exceptions for standalone applications. As the "export.h" header and the "stubs.c" source files are required to implement a standalone application, the intention was that these files be covered by the licensing exception. This is made clear in the following quotes from that email:
"exports.h" should be added to the "allowed" file list; there should be no need to include "common.h". Eventually this needs fixing. Patches are welcome.
"examples/standalone/stubs.c" should be added to the "allowed" file list (the ppc_*jmp.S files are LGPLed).
There should be no doubts - the intention is clear, the current state may need improvement. Help (read: patches) welcome.
