Well, thank *you*! There were a lot of iterations on this patch series, a lot of work, probably a lot of time waiting for compilations to finish ;-), and then a lot of time waiting for the thing to be finally merged. >> I didn’t merge the cross-libtool patch and this one: >> >> Jan Nieuwenhuizen <jann...@gnu.org> skribis: >> >>> * gnu/packages/ncurses.scm (ncurses)[MINGW]: Build with libtool, as >>> recommended; enables dlopen'ing. >> >> I’m not sure what this means (and the explanation should be as a comment >> in the code).

When we have ‘guix pack’ (a generalization of “make guix-binary.x86_64-linux.tar.xz”), that will be a simple way to transfer a bunch of store items to a Windows box. Besides, having a test that runs guile.exe in Wine could be useful. (Though now that Windows implements the Linux syscalls we should make sure the investment is worth it!) Ludo’.
