This patch is to be applied on top of 'next', because to work as intended
(especially for --mandir=<path> option to ./configure) it needs
  Allow INSTALL, bindir, mandir to be set in main Makefile
  e14421b9aa85f11853a0dacae09498515daab7b8
patch (commit) to be present.

For now the following options do actually something:
	$ ./configure 
           --prefix=<prefix>         # [/usr/local]
           --exec_prefix=<prefix>    # [PREFIX]
           --bindir=<bindir>         # [EPREFIX/bin]
           --datadir=<datadir>       # [PREFIX/share]
           --mandir=<mandir>         # [PREFIX/man]

	$ ./configure --help         # hardcoded version 1.4.1

QUESTION: how to make autoconf _generate_ correct version string?

Next patch will show how this infrastructure can be used.

+Alternatively you can use autoconf generated ./configure script to
