Hi,
the FSF is located in Free Software Foundation, 31 Milk Street, #960789,
Boston, MA 02196 USA.
Older GPL licenses contained that mail address ("51 Franklin Street,
Fifth Floor, Boston, MA 02110-1301 USA"), which is no longer valid.
Therefore, the FSF updated their licenses to point only to their webpage
has someone has noticed, cf:
https://gist.github.com/jwilk/435e32788d9d50aba7fc607a6e3d079f
While not mission critical, it seems to make sense to update (some of)
the files in GCC to fix that dangling reference.
It shows up in:
* license text (COPYPING, gcc/COPYING),
* in referrals to those files ("see file ... If not, write to") as
comments in several files
* as one-line copyright-owner statements
* as publisher address for documentation
In total, "Franklin Street" shows up (in GCC mainline) in 1632 files,
albeit only 212 files are not under an testsuite/ subdirectory.
It seems as if at least updating the documentation like
https://gcc.gnu.org/onlinedocs/gfc-internals.pdf (shows up on the second
page) - and the COPYPING + gcc/COPYING files would be sensible.
Thoughts?
Tobias
