-/**
- * compiler - macros for common compiler extensions
- *
- * Abstracts away some compiler hints.  Currently these include:
- * - COLD
- *	For functions not called in fast paths (aka. cold functions)
- * - PRINTF_FMT
- *	For functions which take printf-style parameters.
- * - CONST_FUNCTION
- *	For functions which return the same value for same parameters.
- * - NEEDED
- *	For functions and variables which must be emitted even if unused.
- * - UNNEEDED
- *	For functions and variables which need not be emitted if unused.
- * - UNUSED
- *	For parameters which are not used.
- * - IS_COMPILE_CONSTANT()
- *	For using different tradeoffs for compiletime vs runtime evaluation.
- *
- * License: CC0 (Public domain)
- * Author: Rusty Russell <rusty@rustcorp.com.au>
- *
- * Example:
- *	#include <ccan/compiler/compiler.h>
- *	#include <stdio.h>
- *	#include <stdarg.h>
- *
- *	// Example of a (slow-path) logging function.
- *	static int log_threshold = 2;
- *	static void COLD PRINTF_FMT(2,3)
- *		logger(int level, const char *fmt, ...)
- *	{
- *		va_list ap;
- *		va_start(ap, fmt);
- *		if (level >= log_threshold)
- *			vfprintf(stderr, fmt, ap);
- *		va_end(ap);
- *	}
- *
- *	int main(int argc, char *argv[] UNNEEDED)
- *	{
- *		if (argc != 1) {
- *			logger(3, "Don't want %i arguments!\n", argc-1);
- *			return 1;
- *		}
- *		return 0;

- *	// Out-of-line version.
- *	const char *greek_name(enum greek greek);
- *
- *	// Inline version.
