-** The next definitions activate some tricks to speed up the
-** conversion from doubles to integer types, mainly to LUA_UNSIGNED.
-**
-@@ LUA_MSASMTRICK uses Microsoft assembler to avoid clashes with a
-** DirectX idiosyncrasy.
-**
-@@ 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).
