licensing linking exception mentioned in (most) README files but not in code headers

[jonassmedegaard]

The GPL linking exception is not mentiond in code headers.

Licensing statements in code headers are commonly considered as superseding project-wide licensing statements e.g. in a README file.

Licensing in a LICENSE file is commonly considered as a collection of licensing information - so when it contains the GPL license and a licensing exception, and code headers state that their licensing is GPL and refer to the LICENSE file for details, it can be interpreted as those code files do not permit lining exceptions regardles of the existence of such exception in the referenced LICENSE file.

I recommend to expand the licensing statements in code headers to mention linking exception where appropriate.
