wip/eic 4.3.0 NetBSD

EiC is a freely available C language interpreter in both source and binary form. EiC allows you to write C programs, and then "execute" them as if they were a script (like a Perl script or a shell script). You can even embed EiC in your own programs, allowing your application to have a "scripting" language that is syntactically equivalent to C. It is also possible to let an EiC "script" call compiled library code and for compiled code to make callbacks to EiC user defined functions.
