I have written compile time compliance validation tests for:

	7.12 Mathematics (macros and constants)
	7.12.3 Classification macros
	7.12.4 Trigonometric functions
	7.12.5 Hyperbolic functions
	7.12.6 Exponential and logarithmic functions

They test that things that are supposed to be defined are defined,
and they enforce type checking for defintions that are in scope at
the time the code is compiled (assuming you make the compiler gripe).

In case someone wants to work on this, I can send you a tar-ball.
