ghc-7.4.1-rc1 recompilation checking

Hi, full recompilation with ghc-7.4.1-rc1 is already triggered by a changed "-o" option, which is inconvenient when creating different binaries with shared modules. (see below) It is no problem if I always omit the -o option and get binaries named like my input file, though. Can/should this behaviour of ghc-7.4 be relaxed? Cheers Christian -bash-3.00$ ghc B -o b [1 of 2] Compiling C ( C.hs, C.o ) [2 of 2] Compiling Main ( B.hs, B.o ) Linking b ... -bash-3.00$ ghc A -o a [1 of 2] Compiling C ( C.hs, C.o ) [2 of 2] Compiling Main ( A.hs, A.o ) Linking a ...
