I have no problem with such solution.

Yep, I mean the make dist from the scratch; i.e. what one usually
does when creating new release. The compression is used very r

I didn't make any testing, but the report came from the observation
that result was +300kb on 9 mb. The compression was slow, but
decompression is not affected.

Compared to the total time of make dist its IMHO
acceptable. But configurability won't hurt of course.

Hi,
the newly added dist-xz target produce worse compressed archives
than lzma-dist. The reason is that automake call lzma with
best compression while it won't use -9 level for xz.
Is this intention or bug?
