--  This package provides target dependent definitions of constant for use
--  by the GNAT.Sockets package (g-socket.ads). This package should not be
--  directly with'ed by an applications program.

--  This is the version for alphaev56-dec-osf5.1
--  This file is generated automatically, do not modify it by hand! Instead,
--  make changes to gen-soccon.c and re-run it on each target.
