#undef M undefine M
#if (condition) conditional compiling
#ifdef M compiled if M is defined
#ifndef M compiled if M is not defined
#elif (condition) conditional compiling
#else conditional compiling

defined() is macro defined.
 !defined() is macro not defined
M ## D combines M and D into MD
#M treat M as string "M"
