return value w.r.t. RETSIGTYPE

[Werner LEMBERG]

The standard definition of a signal handler is

  RETSIGTYPE
  handler()
  {
    ...
  }

according to autoconf.info.  Now assume that AC_TYPE_SIGNAL defines
RETSIGTYPE as int.  Picky compilers then give a warning `control
reaches end of non-void function'.  I see no elegant solution to
suppress the message.  How do you expect to solve this?

What about defining RETSIGTYPE_RETURN, to be either void or, say, `1'?

  RETSIGTYPE
  handler()
  {
    ...

    return RETSIGTYPE_RETURN;
  }

PS: Please don't say `just ignore the warning'.  Even gcc is going
    more and more picky...
