Remove a broken attempt to cope with someone #undef'ing __has_include_next.
...
This was broken because __has_include_next(...) would not be valid in a
preprocessor condition if __has_include_next is not defined.

Expand #include_next in float.h from mingw to _msc_ver.
...
A test for this is checking if this compiles:
#include <float.h>
inline bool IsFinite(const double& number) {
return _finite(number) != 0;
}
That depends however on either mingw or msvc being installed, and
chapuni tells me there might be issues with float.h on mingw, so
no automated test is added.
