ghc --make on Haskell and non-Haskell inputs can silently clobber input

Create any valid files A.hs and A.c, then run ghc --make A.hs A.c. You'll get one A.o file for A.hs; the A.o from A.c is lost to the sands of time.

I thought this situation would be pretty unlikely but geekosaur mentioned to me that he had seen someone run into this problem before.
