Implicit return types were removed in C99 with no prior deprecation in
C90.  But I don't particularly care for this warning suppression, since
code using a missing return type but meaning "void" was dodgy anyway.

(In C99 mode the implicit return type diagnostic is mandatory and cannot
be turned off with -Wno-return-type.)
