AutoGen + Guile for fixinc maintenance

[Richard Stallman]

    This means their situation would not change no matter what.
    All variations of AutoGen require bi-directional pipes to
    subprocesses.  That is not DOS.  :-(

Please correct me if I am wrong; it appears that the situation is

* Converting to AutoGen 5 would make no difference on MSDOS
since they can't run either version.

* Converting to AutoGen 5 would make little difference on Windows
because fixinc is not used on Windows.

Given these facts, we should definitely upgrade the script.  Even if
*maintenance* of AutoGen 4 takes "no work", the need to continue
distributing it complicates the overall system and creates various
opportunities for confusion.
