No, I don't. But I know that GNU/Hurd has no support for anything systemd-
related at all. And the build with it enabled failed miserably.

I've now built the tarball and that went OK. Also after make distclean;
configure; make all was fine. 

However rebuilding the git from today crashed the box hard: Console output:
/hurd/crash: src/bootstrap-emacs -Q(1172), signal {no:11, code:1, error:1},
exception {1, code:1, subcode:3496312}, PCs: {0x818d803, 0x51db97c}, Killing
task. <and four more similar entries>. This might be a Hud bug or memory
exhaustion.
