Fix -Wfloat-conversion C warnings on mingw in clamp_double_to_int64. We just have to suppress these warnings: Mingw's math.h uses gcc's __builtin_choose_expr() facility to declare isnan, isfinite, and signbit. But as implemented in at least some versions of gcc, __builtin_choose_expr() can generate type warnings even from branches that are not taken. Fixes bug 22801; bugfix on 0.2.8.1-alpha.

o Minor bugfixes (compilation):
- When building with certain versions the mingw C header files, avoid
float-conversion warnings when calling the C functions isfinite(),
isnan(), and signbit(). Fixes bug 22801; bugfix on 0.2.8.1-alpha.
