So I understand correctly the gcc.pot is used for something and that the
cannot tail call but not the various reasons for it. So this N_ marco
is a way to get debugging or symbol information or something more like:
error_at (EXPR_LOCATION (call_expr),N_("cannot tail-call: %s"),
gcc.pot for that line is:
#: calls.c:1516
▸ prev-zlib/ |16905 #, gcc-internal-format, gfc-internal-format
▸ stage1-fixincludes/ |16906 msgid "cannot tail-call: %s"
▸ stage1-gcc/ |16907 msgstr ""
This seems wrong to me but I am new so double checking would be nice. Or our to talking
about all lines in gcc.pot requiring something similar? I am a bit confused by is it
just this area or all of the output that needs fixing in gcc.pot?

I ran the test suite and got no known new failures. I assumed that I didn't need
to report that but if so that's fine. This is something I always do if possible.
Thanks for the quick reply,
