[tex-live] K&R C compilers.

pdftex needs ANSI C++ and C compilers. Just look at libs/xpdf/README:

    Compatibility
    -------------
    ...
    much any system which runs X11 and has Unix-like libraries.  You'll
    need ANSI C++ and C compilers to compile it.

And I think that many other parts in TeX Live just won't compile if you
don't use an ANSI C compatible compiler.

So, I don't think that we'd loose much if you'd drop support for pre-ANSI
compilers.
