Usually such things just go to the list (which is open to
non-subscribers).

Right. We don't commit the configure script, as it is auto-generated.
You need to either:

  1. Build from a release tarball which contains the "configure" script.

  2. Run "autoconf" to generate the configure script (obviously this
     implies that you have GNU autoconf installed).

  3. Just run "make" without configure. You may need to tweak some
     settings if you don't have some optional libraries installed. See the
     top of Makefile for details.

That does blame to me, but if you "git show c591d5f3" you will see that
I was just tweaking the entries, and the original "configure" line
predates me. Try the "blame parent" option of "git gui blame" or "tig",
and you will see that 5566771 (the original commit adding autoconf
support) is actually responsible. So yes, it has been intentionally
ignored since the beginning.

To add to this excellent reply, I should mention the

  make configure

command.  This runs autoconf, also filling in the version number for
correct ./configure --help output. :)

See the README and INSTALL files for more details.

Hope that helps,
