-odir behaviour change in 6.4.1?

Is this change in behaviour between ghc-6.4 and ghc-6.4.1 desired: ~/trans $ ls foo foo.c ~/trans $ ghc-6.4 -odir foo -c foo/foo.c ~/trans $ ls foo foo.c foo.o ~/trans $ rm foo/foo.o ~/trans $ ls foo foo.c ~/trans $ ghc-6.4.1.20050804 -odir foo -c foo/foo.c ~/trans $ ls foo foo foo.c ~/trans $ ls foo/foo foo.o It seems to break cabal-1.1.1, in the case that I have something like c-sources: foo/foo.c in my .cabal file ...
