Fix for bug #28240: "isinf()" cannot be used in C++ for lack of prototype

Browse source 
Since isinf() portability across various platforms and compilers is a complicated question, we should not use it directly. Instead, the my_isinf() macro should be used, which is defined as an alias to the system-defined isinf() if it is safe to use, or a workaround implementation otherwise.
