Thank you for pointing this out. I previously saw references to such a
"NaN Trick", but without realizing what it means.
While trying to compare the memory usage of Lua 5.1 and 5.2, I
realized that the trick was not active on my build, because Microsoft
compilers do not define any of the tokens from (__i386__,  __i386,
__X86__). So you should add _M_IX86 to that list.
