なんだかよく使うのでメモ。

define.h

#if defined(_WIN32) || defined(_WIN64)
#
#  define OS_WINDOWS
#
#elif defined(__APPLE__)
#
#  include "TargetConditionals.h"
#  if TARGET_OS_IPHONE
#    define OS_IOS
#  else
#    define OS_OSX
#  endif
#
#elif defined(__ANDROID__)
#
#  define OS_ANDROID
#
#elif defined(__linux)
#
#  define OS_LINUX
#
#else
#
#  error unsupported platform
#
#endif
