# This test case is from Morten Elo Petersen. It's harder because
# blib-case1only actually exists in the build dir after the -c, so the
# Dir scanner finds it and adds it to the dir's entries.
# Unfortunately FS.py's File.exists() method checks it later and finds
# it looks like a stale build copy of a missing source, so it deletes
# it. And then it's later discovered to be missing since it's still
# in the dir's entries list. The fix for this is to test for missing
# source files in the dir scanner (Scanner/Dir.py), and delete them
# (just like File.exists() does if they're found in the build dir
# rather than making entries for them.
