`int isnan(double)` is a POSIXism
- `isnan` is something relatively new. We need to provide one for
those systems without it. However:
- X/Open defines `int isnan(double)`. Note the `int`.
- C99 defines `isnan(x)` to be a macro.
- C++11 nukes them all, undefines all the "masking macro"s, and
defines its own `bool isnan(double)`. Note the `bool`.
- In C++, `int isnan(double)` and `bool isnan(double)` are
incompatible.
- So the mess.

include/ruby/missing.h: defined(__cplusplus) before using __cplusplus
* include/ruby/missing.h (isinf, isnan): For non-C++ programs,
defined(__cplusplus) may be needed before using __cplusplus.
