Hi,

I tried to build the latest (unreleased) snapshot of p11-kit for testing
purposes.

I used this command to produce an experimental snapshot:
  git archive --prefix=p11-kit-0.23.3.test/ \
    -o /tmp/p11-kit-0.23.3.test.tar.gz HEAD

I found that the file is much smaller than regular release files.

Not knowing what your usual release procedure is, to include those additional
files, I ran 
  autoreconf -vfi
  ./autogen.sh
which worked to produce the missing files.
