This is wrong. The *A functions deal with ascii strings, whereas 
the *W functions deal with unicode strings. Functions that 
neither return nor accept strings do not have A/W variants.

Also, __WIN32__ does not indicate a 32-bit platform. 
Traditonally, it referred to the Win32 API, which once upon a 
time did mean a 32-bit platform, but officially that API is now 
referred to as the "Windows API", a combination of Win32 and 
Win64. __WIN32__ is always defined even on 64-bit Windows. You 
can read more about the difference here at the MS technet[1].

Essentially, any Win32 API modules created to interface D with 
that API can be used on both 32- and 64-bit. The functions are 
the same.
