Did you have a look at the layout? Most ST provided headers are now in their
own stm/vendor directory.

The files need to be downloaded from different places, with lot of junk to
be removed. Pathes have to be adapted, some definitions added. Requiring the
user to do so will put many obstacles in his way. And providing a batch file
to do so is error prone. So a loud voice to distribute the headers in
question with the ethernut code.

But back to my original question: Does every file written by us but
including the ST headers need to have the ST license tag in the
configurator? As long as we compiled ST code (system_stm32xxxx.c) it is
enough to tag that code with the license requirement in th configurator.
Without accepting the license the user will get a non-functional nut-os
library with non-functional startup code.

Requiring the license acceptance in the configurator on every piece of (our)
code  using the ST header is then superflous in my eyes.
