Here's the list of build errors (in libstdc++-v3 only) on my UDK target.
(Note that is largely C99 on by default.)

csqrt and csqrtf are still remnants of the "can't define your own NAN
	 and nan() becuase C99 already gives them to you" problem that you were
	 working on.

The "We need FINITE_P" is becuase the vendor math.h has

	#ifdef __cplusplus
	extern "C++" {
	inline int isfinite(float __1){ return __fpclassifyf(__1) & FP_FINITE; }
	inline int isfinite(double __1){ return __fpclassify(__1) & FP_FINITE; }
	inline int isfinite(long double __1){ return __fpclassifyl(__1) & FP_FINITE; }
	...
	#else
	#define isfinite(a) blah

	So, since we're C++, we aren't finding the vendor isfinite().

I don't know what this is all about:

Once we have this one under control, I guess we'll tackle the
multilibbed target and its dwarf-1 issues...
