Unfortunately, rebaseall is a rather limited workaround, rather than a
solution for these issues (for reasons which have been discussed extensively
in the past)

I've been considering, as a temporary solution, changing the XWin server to
use system() rather than pipe() & fork() to invoke xkbcomp, which should work
around this problem until the upstream X server changes to using libxkbcommon,
which will avoid the need to run xkbcomp entirely.

(Although I imagine this will just transform the problem reports from "I can't
start the X server" (as it can't successfully fork() xkbcomp) to "I can't
start anything from the X server traymenu" (as it can't successfully fork()
those programs)

I've build a snapshot with this change and uploaded it at [1], perhaps you
could try that out and see if that makes a difference for you.

(Since this snapshot is based on RC2 for the forthcoming 1.10.2 release, it
also contains some upstream GLX changes which might break GLX on XWin which I
haven't had a chance to test yet)
