Hi Ralf,
Thanks a lot for doing that!
I'll be happy to apply it once those changes hit master.
I tried that patch, reproduced the failure, and tracked it down
to what must be a change in how the internal (to 'make check's
Makefile code) $tst variable is set. Before CuTmpdir would get
a directory based on builddir, but the new $tst is in $srcdir,
and part of "make distcheck"s job is to ensure that nothing modifies
srcdir, so it makes the whole tree read-only. Then, CuTmpdir's
attempt to create a temporary directory for "make check" would fail.
If I make the following change, to use "$f" instead (also undocumented),
"make distcheck" passes once again:
