  This function cannot be called from plain inline or extern inline functions
  on some platforms:
  macOS 10.8.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and therefore cannot
  accommodate all Unicode characters.
  @mindex c32_apply_type_test
  However, the Gnulib function @code{c32_apply_type_test}, provided by Gnulib
  module @code{c32_apply_type_test}, operates on 32-bit wide characters and
  therefore does not have this limitation.
  @end itemize
