Not tying ourselves at all. This just gives users who install gcc manually with the ./configure process a default to use and only if they are using the download prerequisites script which is optional. Distributions can still provide multiple choices with package managers. The final tie is at link time where a user may specify any compatible library they choose. We do have a base of users who do not use package managers by the way. So the goal is a minimal installation of a fully functional Fortran. Jerry
