+/* _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)
