3#
4# Our current make(1)-based approach to dependency tracking cannot cope with
5# certain source tree changes, including:
6# - removing source files
7# - replacing generated files with files committed to the tree
8# - changing file extensions (e.g. a C source file rewritten in C++)
9#
10# We handle those cases here in an ad-hoc fashion by looking for the known-
11# bad case in the main .depend file, and if found deleting all of the related
12# .depend files (including for example the lib32 version).
13#
14# These tests increase the build time (albeit by a small amount), so they
15# should be removed once enough time has passed and it is extremely unlikely
16# anyone would try a NO_CLEAN build against an object tree from before the
17# related change.  One year should be sufficient.
