WIN64 or _WIN64 or _NI_mswin64_

[JGS]

I have some code that is almost identical for 32- and 64-bit application.

Which is the best definition for selection (using #if 😞

WIN32 and WIN64, or

_WIN32 and _WIN64, or

__WIN32__ and __WIN64__, or

_NI_mswin32_ and _NI_mswin64_

I am using CVI2010 on Windows 7 x64.

I build only only for WIndows (Windows XP 32, and 32- and 64-bit for Windows 7)

Sometimes I use the Windows SDK as provided by CVI.
