+/* _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)
