[Olsr-dev] [PATCH v1 05/12] Makefile: WARNINGS: add -Winit-self

[Ferry Huberts]

From: Ferry Huberts <(spam-protected)>

-Winit-self (C, C++, Objective-C and Objective-C++ only)
   Warn about uninitialized variables which are initialized
   with themselves.  Note this option can only be used with
   the -Wuninitialized option.

   For example, GCC will warn about "i" being uninitialized
   in the following snippet only when -Winit-self has been
   specified:

           int f()
           {
             int i = i;
             return i;
           }
