[Pkg-scicomp-devel] Bug#439147: Bug#439147: libglpk0: some routines emit messages even with GLP_MSG_OFF set

Rafael,

I released the version 4.21 to-day, where the bug reported has been
fixed. Please see the announce attached.

(Making a patch would be problematic, because the source code was
changed in many places since 4.20.)

Best regards,
