Use __printflike() and __dead2 instead of hard-coded gccisms.

Declare perror().  We define and use a home made version of perror(3)
that can't simply be removed (although it has the same interface as
perror(3)) since it is very different (it prints on stdout, doesn't
always print the program name, and sometimes exits).  Declare it to
get a reminder of this brokenness when WARNS is increased enough.
