But should std::signbit be available as ::signbit when <math.h> is included, at
least for c++0x mode?
[depr.c.headers]/2 says
"Every C header, each of which has a name of the form name.h, behaves as if
each name placed in the standard library namespace by the corresponding cname
header is placed within the global namespace scope."
signbit is placed in namespace std by <cmath> which says to me that it should
be placed in the global namespace by <math.h>
(I'm still unsure whether the same applies to <stddef.h> and std::nullptr_t)
