- New INSTALL document describing different ways to build "tunala" and
possible problems.
- New file breakage.c handles (so far) missing functions.
- Get rid of some signed/unsigned/const warnings thanks to solaris-cc
- Add autoconf/automake input files, and helper scripts to populate missing
(but auto-generated) files.
This change adds a configure.in and Makefile.am to build everything using
autoconf, automake, and libtool - and adds "gunk" scripts to generate the
various files those things need (and clean then up again after). This means
that "autogunk.sh" needs to be run first on a system with the autotools,
but the resulting directory should be "configure"able and compilable on
systems without those tools.
