      The 'int x=x' style statement do not make sense and cause problems with
some compilers.  Replace it with more sensible initializers to ensure
the value have a well known starting point.  Using initializers
proposed by Timothy B. Terriberry in !25.

Added -Werror=uninitialized -Winit-self to default GCC build to ensure
this style of statement do not sneak into the code again.

Fixes #2317
