- We now define KEY_WOW64_32KEY and KEY_WOW64_64KEY locally, if on MinGW
- We use variadic macros on VS2005 and newer as well as on MinGW instead of the NOP_FUNCTION construct
```Lua
local p = [[HKEY_LOCAL_MACHINE\SOFTWARE]]
local key = assert(winreg.openkey(p, 'r'))
local key64 = assert(winreg.openkey(p, 'r64'))
local key32 = assert(winreg.openkey(p, 'r32'))
```
