# Makefile
#    Makefile for src/port
#
# These files are used by the Postgres backend, and also by frontend
# programs.  Primarily, they are meant to provide portability on systems
# with broken/missing library files.
#
# This makefile generates three outputs:
#
#	libpgport.a - contains object files with FRONTEND defined,
#		for use by client applications
#
#	libpgport_shlib.a - contains object files with FRONTEND defined,
#		built suitably for use in shared libraries; for use
#		by frontend libraries
#
#	libpgport_srv.a - contains object files without FRONTEND defined,
#		for use only by the backend
#
# LIBOBJS is set by configure (via Makefile.global) to be the list of object
# files that are conditionally needed as determined by configure's probing.
# OBJS adds additional object files that are always compiled.
