######################################################################
### barrier is a helper target that can be used to separate targets
### that should be built in a new make process from being built in
### the current one.  The targets that must be built after the "barrier"
### target invokes a new make should be listed in _BARRIER_POST_TARGETS,
### and should be of the form:
###
###	.if !defined(_PKGSRC_BARRIER)
###	foo: barrier
###	.else
###	foo: foo's real source dependencies
###	.endif
###
### Note that none of foo's real source dependencies should include
### targets that occur before the barrier.
