Rene Liebscher: 

* use self.debug_print() for debug messages
  * uses now copy.copy() to copy lists
  * added 'shared_lib_extension=".dll"', ... , this is necessary if you
    want use the compiler class outside of the standard distutils build
    process.
  * changed result type of check_config_h() from int to string
