@@ LUA_IEEE754TRICK uses a trick that should work on any machine
** using IEEE754 with a 32-bit integer type.
**
@@ LUA_IEEELL extends the trick to LUA_INTEGER; should only be
** defined when LUA_INTEGER is a 32-bit integer.
**
@@ LUA_IEEEENDIAN is the endianness of doubles in your machine
** (0 for little endian, 1 for big endian); if not defined, Lua will
** check it dynamically for LUA_IEEE754TRICK (but not for LUA_NANTRICK).
**
@@ LUA_NANTRICK controls the use of a trick to pack all types into
** a single double value, using NaN values to represent non-number
** values. The trick only works on 32-bit machines (ints and pointers
** are 32-bit values) with numbers represented as IEEE 754-2008 doubles
** with conventional endianess (12345678 or 87654321), in CPUs that do
** not produce signaling NaN values (all NaNs are quiet).
