Hello list,

as the title says, I believe running "make dist" should fail when tar 
fails. The problem is that because there is a shell pipeline with gzip, 
the exit code of the pipeline is 0. I'm not aware of a portable way to fix 
this (named pipes maybe?), but most convenient would be bash's "set -o 
pipefail".

Relevant output from "make V=1 dist":

tardir=cfengine-3.7.0a1.5ffcc54 && tar --format=ustar -chf - "$tardir" | GZIP=--best gzip -c >cfengine-3.7.0a1.5ffcc54.tar.gz

(A separate bug report will come soon about the "link failure" despite tar 
"-h" option being used.)


Thanks,
Dimitris
