--- Comment #26 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
One more datapoint on the .smod / .mod issue.
I ran into the first package that fails to build with 6.0 because of this.
libxc (version 2.2.2, Tobias Burnus actually being one of the authors), relies
on a configure macro named ax_cv_f90_modext this macro now leads in the
Makefile to :
[...]
am__untar = $${TAR-tar} xf -
ax_cv_f90_modext = mod
smod
bindir = ${exec_prefix}/bin
[...]
which leads to an obvious:> make -j
Makefile:319: *** missing separator. Stop.
While arguably this is a bug in the ax_cv_f90_modext macro, it might be
indicative of possible problems 'in the wild'.
However, I do like the idea of having only public info in the .mod, and hence
improving the recompilation cascade problem.
