The is another similar problem. Let's say I have an up-to-date compiled program and I want to recompile it with profiling turned on. In older ghc version adding -prof option caused all modules to be recompiled and the whole application relinked. Now I have to manually delete the application binary to force recompilation or use -fno-recomp. BTW. The -fno-recomp option has a very unintuitive name, at least for me. When I see "-fno-recomp", my brain thinks "no recompilation", meaning "no unneccesary recompilation", which is what --make does by default. Using "-fno-recomp" causes all modules to be recompiled, whether they changed or not. I think one of -frecomp or -fno-recomp-checking would be much clearer. But it's probably too late to change that...
