... when used as

    [...] --batch --eval '(batch-byte-recompile-directory 0)'

But as

    [...] --batch --eval '(batch-byte-compile)' `find . -name '*.el'`

the non-zero exit status is available. Could "make check" use this to
indicate a compilation error?

Alternatively of help may be a new optional parameter for
byte-recompile-directory to return its fail-count instead of nothing
useful as now and batch-byte-recompile-directory would then also on
request use it for (kill-emacs fail-count) instead of only the current
undifferentiated (kill-emacs 0).
