Subject: C99 compatibility fixes for gnupg 1

--
Include <stdlib.h> for the exit function.  This avoids a failing
GNUPG_CHECK_IPC check in case the compiler no longer supports implicit
function declarations.

Explicitly declare the return type of main as int.  This too avoids
failures with future compilers.
