>Description:
	printf(3) does not properly handle the "long double" type
	when it is not equivalent to the "double" type.

	This causes GCC 3.3's libstdc++-v3 to get incorrect
	numeric limits (shows up as testsuite failures).

>How-To-Repeat:
	Compile the following program with GCC 3.3:

int
main()
{
        printf("sizeof double = %d\n", sizeof(double));
        printf("sizeof long double = %d\n", sizeof(long double));

        printf("double max = %g\n", __DBL_MAX__);
        printf("long double max = %Lg\n", __LDBL_MAX__);

        return 0;
}

	...and run it:

sizeof double = 8
sizeof long double = 12
double max = 1.79769e+308
long double max = inf
