bmake will not think that object files such as read.o are out of date
due to common.h changing since the dependency is only recorded in
.depend.kqtest.read.o in an old object directory.

# Our current make(1)-based approach to dependency tracking cannot cope with
|
|
# certain source tree changes, including:
|
|
# - removing source files
|
|
# - replacing generated files with files committed to the tree
|
|
# - changing file extensions (e.g. a C source file rewritten in C++)
|
|
#
|
|
# We handle those cases here in an ad-hoc fashion by looking for the known-
|
|
# bad case in the main .depend file, and if found deleting all of the related
|
|
# .depend files (including for example the lib32 version).
|
|
#
|
|
# These tests increase the build time (albeit by a small amount), so they
|
|
# should be removed once enough time has passed and it is extremely unlikely
|
|
# anyone would try a NO_CLEAN build against an object tree from before the
|
|
# related change. One year should be sufficient.
