It successfully built (and runs) for me today on 9.3_STABLE/amd64.
pkgsrc is as of roughly two days ago, when I kicked off the pbulk build
in question. I have not forced GCC to 10 in my pkgsrc settings, so it's
going with the defaults across the board.

I also checked the MNX builk builds for 9.99.106; there it's failed for
an entirely different reason that seems to be a local packaging thing.
