 Thank you. I will certainly need help re Intel part: this is not something
 I am able to do.

 I will check re force deactivation (point 4).
 As for point 3, ''all'' libgcc build fine, though I am not sure we need
 silly ports that do not install anything but take several hours to build –
 just to delete its build directory, leaving a line in the registry. AFAIR,
 `libgcc8` installs exactly nothing. `libgcc9` installs extensions dylibs,
 though those perhaps should be installed by `libgcc10`, if at all needed
 (Iain said we can use symlinks instead). `libgcc10` installs a Fortran
 dylib – again, not sure if that is something needed. `libgcc11` installs
 nothing again.
