# Makefile
#    Makefile for the port-specific subsystem of the backend
#
# These files are used in other directories for portability on systems
# with broken/missing library files, and for common code sharing.
#
# This makefile generates two outputs:
#
#	libpgport.a - contains object files with FRONTEND defined,
#		for use by client application and libraries
#
#	libpgport_srv.a - contains object files without FRONTEND defined,
#		for use only by the backend binaries
#
# 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.
