If these LICENSE_XXX tags are added to the .conf files of the Nut/OS 
distribution, this would not really constitute acceptance of the licence 
would it?

If a user loads a .conf file, for example stm3210e-eval.conf, whith the 
LICENSE tags included in it, then he would not even take notice of this 
fact.

On the contrary if the LICENSE tags are omitted in the STM32 .conf 
files, then compilation of the applications will fail and the user has 
no clue why.

If the tags remain omitted in the .conf files then I suggest to add a 
#error directive to the STM32 headers which checks whether the tags are 
set and if not, give a hint that the user has to add those and by doing 
so accept the license. For example:

#ifndef LICENSE_MCD_ST_LIBERTY
#error You must add the tag LICENSE_MCD_ST_LIBERTY to the .conf file and 
by doing so accept the special license conditions of ST Microelectronics
#endif

Cheers,

Henrik
