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