Sorry again, I'd forgotten, with holiday breaks and things, about the dependency on gfortran being removed. (I'm not sure that's a good idea, since the library is version-specific.) Since I've expurgated the contribution to the closure from valgrind it looks a lot better. Keeping a dependency on gfortran I think would only contribute the "self" of gfortran. That's actually a lot smaller than libgfortran, which has a load of stuff that presumably shouldn't be in it, like libstdc++ and the sanitizer support. > We could discuss that policy of course, but that=E2=80=99s another story. > > Ludo=E2=80=99.
