    util/u_math: Fix C++ include of u_math.h on MSVC.
    
    GNU C++ compiler declares the C99 lrint, etc. when _GNU_SOURCE is
    defined, but MSVC does not.
    
    Trivial.

Thanks Vinson. This should have been fixed with

    util: Fix MinGW build.
    
    _GNU_SOURCE appears to not be used reliably.  Use _MSC_VER instead so
    that MSVC alone is affected.
