>Description:
Currently, NetBSD ships with GCC 10.5 (nb20231008) which is 5 major versions behind. It is not a critical issue, but it would be nice to have it up-to-date and ready to use in a fresh install. It would also be nice to have all compilers available. I found that gfortran is not available with the gcc shipped with the OS.
