--- Comment #7 from Christian Jullien <jullien at eligis dot com> ---
The Solaris ln bug with 8.31 is described on this ticket:
http://lists.gnu.org/archive/html/bug-coreutils/2019-03/msg00045.html

If it is really the root of the reported issue, gcc is only culprit to not
detect broken ln with configure.

With 8.30 gcc continues to (slowly) build on my machine.

It will finish by May, 15 (sic!)
