Janus, this is actually incredibly valuable information. Yes, I was always
since ages building gcc/gfortran/g++ from the svn, and at some point
compilation became significantly ("macroscopically") slower, probably from
version 7.0.0 on. Could this be when enable-checking was introduced. Can I just
compile the svn version with --enable-checking=release?
