# These files are used by the Postgres backend, and also by frontend
# programs.  These files provide common functionality that isn't directly
# concerned with portability and thus doesn't belong in src/port.
#
# This makefile generates three outputs:
#
#	libpgcommon.a - contains object files with FRONTEND defined,
#		for use by client applications
#
#	libpgcommon_shlib.a - contains object files with FRONTEND defined,
#		built suitably for use in shared libraries; for use
#		by frontend libraries
#
#	libpgcommon_srv.a - contains object files without FRONTEND defined,
#		for use only by the backend
