-# [1] this is a hack for GHC <= 6.10.1.  When making dependencies with
-# ghc -M, in GHC 6.10.1 and earlier, GHC needed to find either the .hi
-# file or the source file for any dependency.  Since we build the
-# .depend files before building the packages, we have to make sure GHC
-# can find the source files; hence we have to make sure that the
-# import-dirs field of each boot package points to the sources for the
-# package as well as the dist/build dir.
-#
-# In GHC 6.10.2, we changed the way ghc -M worked so that it doesn't
-# check for existence of the source file, and doesn't look for the .hi
-# file if there is only one possibility for its location.  Which means
-# that we must *not* do that above hack in this case, because there
-# would be multiple locations to search for the .hi file.
