Hi,

Darn. Thanks.

For C only, warn about a "return" statement with an expression in a function whose return type is "void", unless the 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 :(
