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.
