[Debian-med-packaging] Trying to disable error=format-security for clapack

[Gianfranco Costamagna]

http://ftp.kevag-telekom.de/mirrors/gentoo.org/rsync/sci-libs/clapack/files/clapack-3.2.1-noblasf2c.patch

seems that the i_len_trim.c file might be somewhere else, look at gentoo packaging, they seem to have not
stripped it from the tarball I guess.

Does this helps?

its not finally done.

I think the .h files are not a problem.  With my recent changes in Git[1]
there is a problem with the linker when running the clapack test suite:

...

Any further hint?

Kind regards
