Including MSYS so that end users can compile libraries pre-supposes that the solution to the external library problem is having each user compile their own

I see the inclusion of MSYS merely as providing another option. You can't always find a library that suits your requirements - eg it wasn't built with the configuration you wanted, or it's a dynamic library whereas you'd prefer a static library so you can distribute binaries of a module without having to include the dll with the package.

Of course, it's extra bulk to download, and if anyone wants MSYS they can always download it themselves ... hence I refrain from pushing too hard its inclusion.

Good to hear that g77 is planned for inclusion (subject to testing). I definitely think that's as it should be.

Cheers,
