Shouldn't this be if you find the "or any later version" in all files
with GPL (resp. LGPL) header?
Even one file with GPL header without the "any later version" should be
enough to make the whole non-distributable under any later version.
Or are we supposed to put multiple licenses in the tag in that case?
Say for glibc in F7:
License: LGPL2.1+, LGPL2.1/exception, GPL2+, GPL2
(the library stuff is under LGPL2.1 or any later version, except
some files have an exception, so that you can link them even into
proprietary stuff (e.g. crt files, lib*_nonshared.a), then there
are some GPL2 or any later version executables and by mistake
some executables were GPL2only (corrected in 2.6.90)).
