Comment(by simonpj):
OK, here's the plan:
* For GHC 7.0 we will add the `SpecConstr` type (which is very small) to
`GHC.Exts`. That should eliminate the blow-up for clients of `vector`.
* However the main point remains. For 7.2 we'll think about a more
systematic solution using the module-initialisation mechanisms built into
the system linker
Concerning the latter, the main sticking point is that linker
"constructors" must have a C API, and our native code generators don't
know how to generate C-callable procedures. The right thing may be to
generate a C stub file. (The LLVM back end should not have this problem.)
