 Hi

 I am very happy with the -make option. However, I think
 it could be improved even further. I would like ghc to
 be able to compile multiple executables with one
 invocation of ghc, using the -make option.

 Compiling multiple executables in one invokation could
 safe a lot of compile-time, when the executables shares
 most of their source files. I believe the time would be
 saved, as it would remove the need to check all source
 files for possible recompilation for each executable.
 Furthermore, we would also only need to build the
 dependency graph once.
