Hi,

for issues I noticed while working on debug-mode for std::array: avoid 
the inclusion of <cstddef> in two places (in v3 we never include it); 
fix the new check added by Florian vs -fno-exceptions.

Tested x86_64-linux.

Thanks,
Paolo.

	* include/bits/atomic_base.h: Don't include <cstddef>, use nullptr.
	* include/std/atomic: Likewise.
	* include/tr2/dynamic_bitset: Likewise.

	* libsupc++/vec.cc (compute_size(std::size_t, std::size_t,
	std::size_t)): Fix for -fno-exceptions.
