/* _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)
