_THROW not defined in GCC?

Please tell me where the _THROW macro is defined in GCC4 or how to define it manually

#include <stdio.h>
#include <stdlib.h>
#include <stdarg.h>
#include <assert.h>
#include <ctype.h>
#include <climits>
#include <stdexcept>
#include <sys/cdefs.h>
#include <sys/types.h>

void test() { _THROW(std::range_error,"Test"); }

If you want to throw an exception in C++, use the standard C++ throw keyword:

 throw std::range_error("Test");

Please refrain from using some compiler-specific internal macro.

If you must define it, here you go:

#define _THROW(e, ...) throw e(__VA_ARGS__)
