50-use-strict.patch

[Akim Demaille]

I don't know how to fix the `use strict refs' part.  In particular, it
dies on computed sub names:

        & $my_sub ();

fails, and I don't know how to rewrite it the way strict refs wants it.

from  Akim Demaille  <[EMAIL PROTECTED]>
        * automake.in: Use strict vars and subs.
        Declare `%require_file_found'.
        (&handle_source_transform, &make_paragraphs): Declare my variables.
