# 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.
