Hi,

IANAL, that was only no exact proposal what can be in license file.
There is other proposal (the way how LLVM did this license change to
Apache 2.0):

---- Exceptions to the Apache 2.0 License: ——

As an exception, if you use this Software to compile your source code and portions of this Software are embedded into the binary product as a result, you may redistribute such product without providing attribution as would otherwise be required by Sections 4(a), 4(b) and 4(d) of the License.  

In addition, if you combine or link compiled forms of this Software with software that is licensed under the GPLv2 (“Combined Software”) and if a court of competent jurisdiction determines that the patent provision (Section 3), the indemnity provision (Section 9) or other Section of the License conflicts with the conditions of the GPLv2, you may retroactively and prospectively choose to deem waived or otherwise exclude such Section(s) of the License, but only in their entirety and only with respect to the Combined Software.

---- end ---

Would it be acceptable for Apple, for Debian and etc.?
