  /* _GL_UNUSED_PARAMETER is a marker that can be appended to function parameter
     declarations for parameters that are not used.  This helps to reduce
     warnings, such as from GCC -Wunused-parameter.  The syntax is as follows:
         type param _GL_UNUSED_PARAMETER
     or more generally
         param_decl _GL_UNUSED_PARAMETER
     For example:
         int param _GL_UNUSED_PARAMETER
         int *(*param)(void) _GL_UNUSED_PARAMETER
     Other possible, but obscure and discouraged syntaxes:
         int _GL_UNUSED_PARAMETER *(*param)(void)
         _GL_UNUSED_PARAMETER int *(*param)(void)
