#    Makefile for src/common
#
# This makefile generates two outputs:
#
#	libpgcommon.a - contains object files with FRONTEND defined,
#		for use by client applications
#
#	libpgcommon_srv.a - contains object files without FRONTEND defined,
#		for use only by the backend binaries
#
# You can also symlink/copy individual source files from this directory,
# to compile with different options. (libpq does that, because it needs
# to use -fPIC on some platforms.)
