Build broken on Windows x64

[Tobias Hartmann]

Hi Fred,

the Windows x64 build is currently broken due to:
C:\jprt\T\P1\093341.tohartma\s\hotspot\src\cpu\x86\vm\interpreterRT_x86_64.cpp(283) : error C2065: '_num_int_args' : undeclared identifier

        due to following members:
        'void NativeSignatureIterator::pass_valuetype(void)' : is abstract
        C:\jprt\T\P1\093341.tohartma\s\hotspot\src\share\vm\runtime/signature.hpp(326) : see declaration of 'NativeSignatureIterator::pass_valuetype'

The problem is that there are some #ifdef _WIN64 in the code and the WIN64 specific code is not implemented. Is this intended?

Thanks,
Tobias
