# This prevents anything that depends upon the target from being rebuilt
|
|
# if the file did not really change. This is neccessary because these

|
# targets get called forcively as a result of install-headers being a
|
|
# PHONY target. The downside to this 'trick' is if one of our prerequisites
|
|
# has its timestamp updated then make will get confused and always think
|
|
# this build step needs to be redone. But since it is phony and gets redone
|
|
# anyway, who cares!
