Indeed.

Sijmen: See https://wiki.netbsd.org/pkgsrc/gcc/ for discussion.

The short story on the way to succeed for now is:

  First, build a new enough gcc.

  Then, put GCC_REQD=5 (or 6) in mk.conf.

  Then, build everything you need.


As Edgar says, the hard part is making the bootstrap work, and having it
play nice with both regular user usage and bulk builds.
