libtool is part of architecture cross bootstrap since a very long time. Since about 10 years, it is being cross build (with hacks) in https://wiki.debian.org/HelmutGrohne/rebootstrap. This patch is a step towards removing those hacks, so yes, this has been tested for a quite long time. > I was not aware of gfortran-for-host.

The concept was first used by qt5-qmake (without the -for-host naming), later transferred to binutils, eventually reached pkgconf (without -for-host) and just this year reached gcc-VER and gcc-defaults. Please don't change dh-fortran-mod just yet. I also want to see it there, but we need to be more careful there as it is not as isolated as in libtool. Just days ago I started a discussion (https://lists.debian.org/debian-cross/2024/11/msg00000.html) where I explored cross building fftw3 and quickly ended up at dh-fortran-mod and a non-trivial problem. I would very much welcome your input there. The underlying problem is of general nature and Fortran just happens to be affected earlier than others. Can you tell me what list I should have Cced for that discussion to reach you? Helmut
