* Deprecation removals previously specific to MSVC/Intel now also used
by clang
* String literals were assigned to non const pointers. These are stored
in mutable arrays now
* An implicit function pointer to pointer conversion is a Microsoft
extension warning is suppressed by an explicit reinterpret_cast
* The MSVC specific deprecation macro for jsoncpp was moved after the
clang macro to avoid redefinition warnings. This is consistent with
how jsoncpp fixed the issue in 36d8cfd7
