I viewed the new generated gcc.pot by this patch, the changed parts are
the following:
#: cp/pt.c:4667
#, gcc-internal-format
msgid "redeclared with %d template parameter"
msgid_plural "redeclared with %d template parameters"
msgstr[0] ""
msgstr[1] ""
#: cp/pt.c:4671
#, gcc-internal-format
msgid "previous declaration %q+D used %d template parameter"
msgid_plural "previous declaration %q+D used %d template parameters"
msgstr[0] ""
msgstr[1] ""
Just be curious, how the msgstr will be set at the above example Paolo
indicated.
