Thunking is just API translation because of different pointer conventions  
and such. Arguably the existence and usage of Windows-4-style thunking  
between 32-bit and 16-bit components illustratively shows that Windows 4  
is close to its Windows 3 roots.

In x86 Windows NT, 16-bit subsystems known as NTVDM and WOW are enabled by  
default, but they seem to be separated more clearly from the main (32-bit)  
system.
