* Changed "true" to "TRUE" in some file: "true" doesn't exist in BC++ 5

* Added wxDataStream and wxProcess
* Added the asynchronous end process notification on GTK and MSW
* Updated configure* and setup.h
* Added extended.c: Apple code to encode/decode float in IEEE format
  this code is removable by disabling USE_APPLE_CODEC
