What license / licenses are the ChangeLogs of GCC distributed under? This is of practical importance when I want to amend incomplete ChangeLogs or use information from a ChangeLog to complete comments and/or documentation, or want to write a ChangeLog for fixing a misspelling in code or documentation that is not replicated in the ChangeLog entry for the original contribution.
Can I use function names from GPLed code to put them in a ChangeLog? Can I use names of sections or concepts, or misspellings in GFDLed documentation (like {trunk,branch}/gcc/doc/*.texi, which shares its ChangeLog with GPLed code in {trunk,branch}/gcc), to put them in a ChangeLog? Can I use narrative text from a ChangeLog to put it into a comment in GPLed code or in GFDLed documentation? Note, I do not reside in the USA, so AFAIC I can't use the USA's 'fair use' provisions directly. (If someone else uses them to effectively relicense affected matter, I suppose I can work with the resulting work).
