Improvement for 64bit Windows port (#1011)

Browse source 
* 64bit TickType_t is supported on Windows port.(MSVC and MinGW)
Especially it is introduced for 64bit compiler.(x64 platform on MSVC and MinGW-w64)

* Unnecessary compiler warning for the cast operation is disabled locally.(MinGW-w64 only)

* Modify the condition for ignoring compiler warning for the cast operation.

Before modification: Compiler warning was ignored only on MinGW64
After modification: Compiler warning is ignored on MinGW32 and MinGW64
Reason of modification: The cast warning here is unavoidable not only on MinGW64 but also on MinGW32.
"__GNUC__" macro is used because MSVC does not recognize this #pragma directive.
