Darn.  Thanks.

           For C only, warn about a "return" statement with an expression in a function whose return type is "void",
unlessthe expression type is also
 
           "void".  As a GNU extension, the latter case is accepted without a warning unless -Wpedantic is used.

And no, no thanks to you gcc. -pedantic is entirely unusable. It warns
about extensions we explicitly test for :(

The scary thing is that apparently almost everybody else has followed
gcc's lead on this.
