 Err, please no.  The type of the return value of signal() is not really
 `void (*)' but something more like:
 
         void (*)(int)
 
 But this is not so easy to separate from the name of the signal()
 function without a typedef; at least not without breaking the validity
 of the C declaration, which is a bad thing since then manpage readers
 cannot copy/paste the prototype of signal() from its manpage.
