I would disable this warning only in __cmsis_start() with a push/pop pragma.

Done!

Ideally, the guidelines would be in the RTEMS Software Engineering manual before we added the Apache 2.0 files. We should avoid that every contributor has to figure out what to do. I you think that this __rtems__ stuff is enough, then just document it. Zephyr for example has a clear process to add new licenses:

https://docs.zephyrproject.org/latest/contribute/external.html

Indeed, but we're not living in ideal world unfortunately. Zephyr is completely different league in terms of man-power available to the project. We need to live with what we have.

Anyway, I've submitted new version of the patch and hopefully also be more compliant with the terms of the Apache 2.0 license.

Thanks!
Karel
