# This makefile generates two outputs:
#
#	libpgcommon.a - contains object files with FRONTEND defined,
#		for use by client application and libraries
#
#	libpgcommon_srv.a - contains object files without FRONTEND defined,
#		for use only by the backend binaries

# Because this uses its own compilation rule, it doesn't use the

# dependency tracking works anyway for the *_srv.o files, depend on
# their *.o siblings as well, which do have proper dependencies.  It's
# a hack that might fail someday if there is a *_srv.o without a
# corresponding *.o, but it works for now.
