The file is canonically maintained in GCC svn, then changes are merged
over to the gdb+binutils repository.

If you look at the files in releases, which one is newer will just
depend on which release happened later.

I checked just now and the files are still in sync in the development
repositories.


In the past, GNU was pretty lax about extensions.  Some were not
documented (DW_OP_GNU_uninit), some had the wrong names
(DW_TAG_format_label), etc.  We try to be better about it now.
