--- Comment #7 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
It's the new macro in c++config:

#if __cpp_noexcept_function_type
#define _GLIBCXX_NOEXCEPT_PARM , bool _N
#define _GLIBCXX_NOEXCEPT_QUAL noexcept (_N)
#else
#define _GLIBCXX_NOEXCEPT_PARM
#define _GLIBCXX_NOEXCEPT_QUAL
#endif

See this comment a few lines below in the same file:

// This marks string literals in header files to be extracted for eventual
// translation.  It is primarily used for messages in thrown exceptions; see
// src/functexcept.cc.  We use __N because the more traditional _N is used
// for something else under certain OSes (see BADNAMES).
#define __N(msgid)     (msgid)

Testing trivial fix...
