[cfe-dev] return statements without expressions in non-void functions revisited

[Jack Howarth]

  A more complete test case of the issue we are faced with in compiling texlive
with the strict treatment of return statements without expressions in non-void	functions
is attached. Any chance that the previously proposed -std=c89 warning behavior will be
implemented for clang 3.0?
