It's been awhile...

Not terribly much progress on the cpplib front. Neil's algorithm didn't work right the first time around, got revised, and now there's a new version sitting on my hard drive waiting to be finished up.

I did some work in other areas, like the 'specs' that tell /bin/cc how to run the real compiler (which is hiding in a dark corner of /usr/lib). These are a little language in their own, and not terribly comprehensible - here's a snippet:

    %1 %{!Q:-quiet} -dumpbase %B %{d*} %{m*} %{a*}
    %{g*} %{O*} %{W*} %{w} %{pedantic*} %{std*} %{ansi}
    %{traditional} %{v:-version} %{pg:-p} %{p} %{f*}
    %{aux-info*} %{Qn:-fno-ident} %{--help:--help}
    %{S:%W{o*}%{!o*:-o %b.s}}

With some magic, that turns into an argument vector for one of the programs run during compilation. Not surprisingly, people avoid the stuff as much as possible.

I also stomped the irritating warning bug with built-in functions. You didn't used to get warned if you forget to include <string.h> and use strcpy, because gcc Knows Things about strcpy before it sees any headers. Not anymore. (It was intended to get this right all along, but one if went the wrong way in the mess that is the Yacc grammar for C.)
