ghc-7.4.1-rc1 recompilation checking

[Christian Maeder]

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
