>Description:

there are at least two issues with long double support:

	- isinf() and isnan() work on double's and there is no counter part
	for long double.  these's don't work correctly for long double.

	- printf() (and scanf())'s support for long double is basically
	useless.  internally it simply casts the value to a double before
	processing it.  this causes any value that fits in a long double
	but not a double to fail.

>How-To-Repeat:

	write code that uses (needs) long double support.  see it fail.
