Adds two new external authors to etc/update-copyright.py to cover bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then updates copyright messages as follows: 1) Update cgen/utils.scm emitted copyrights. 2) Run "etc/update-copyright.py --this-year" with an extra external author I haven't committed, 'Kalray SA.', to cover gas testsuite files (which should have their copyright message removed). 3) Build with --enable-maintainer-mode --enable-cgen-maint=yes. 4) Check out */po/*.pot which we don't update frequently.

Unlinks the named file, unless it is special (e.g. a device file).
|

Returns 0 when the file was unlinked, a negative value (and errno set) when
|
|
there was an error deleting the file, and a positive value if no attempt
|
|
was made to unlink the file because it is special.
