Hi Dennis,

you are not missing arguments, but you do need newer fetchmail source
files, and that currently means cloning from Git. Alpha 9 contained some
bugs that show in some configurations, and that have been fixed on the
"next" branch in the Git repositories since then, and I don't think I
will roll other alpha tarballs. Tarballs will likely only happen for
betas or release candidates later on (and releases of course). You do
not want to wait for that if you want OAuth 2 now.

For that, you would need to install git, automake, autoconf, flex,
bison, m4, gettext, and clone from Git instead of downloading a tarball.

The first-time clone takes a little time to download some 10...20 MB (I
don't know how efficiently GitLab or SourceForge packed the repos),
future updates only fetch a few new commits then and are quick. See
https://gitlab.com/fetchmail/fetchmail/-/blob/next/README.git for
repository addresses.

Reason is there have been too many changes since alpha9, and offering
alpha tarballs is currently uneconomical on each and every aspect, and I
do not want to encourage one-off builds of an alpha branch that then
rots. And the socket.c source file alone has a dozen or so changesets
that are relevant to OpenSSL use.

Development targets recent releases of major Linux or BSD distributions
such as Fedora Linux, Debian Linux, FreeBSD and maybe derivatives.
Long-Term-Support releases may be too old unless released recently.
Up-to-date rolling releases such as Gentoo or Arch Linux or openSUSE's
rolling release branch should be good, too. Every once in a blue moon I
also try OpenIllumos Hipster and OpenBSD, but that usually happens
closer to release or if somebody points me to an issue. Alpha versions
of fetchmail are irrelevant to past releases of distributions, so I can
take the liberty of expecting the latest distro releases.

In order to avoid further accidents, I have removed most alphas except
for the more than 10-year-old alpha2+MAPI that carried a failed MAPI
attempt from a Google Summer of Code project ages ago. It is unusable
but I wanted this museum as a warning what happens when neither the
mentor nor the GSoC student (mentee) communicate properly with the
upstream and the changes need integration and testing.

Regards,
Matthias
