There is a redefined warning when compile like below:

In file included from tomoyo-diffpolicy.c:23:0:
tomoyotools.h:26:0: warning: "_GNU_SOURCE" redefined
  #define _GNU_SOURCE
  ^

  #define _GNU_SOURCE

The _GNU_SOURCE is ready defined in the source and there is not ifdef or 
ifndef for it in the source.
