[-- Attachment #1: Type: text/plain, Size: 5498 bytes --]

This is infrastructure update for configure / build of vector math library.

2014-12-02  Andrew Senkevich  <andrew.n.senkevich@gmail.com>

        * Makeconfig: Added mathvec folder.
        * configure.ac: Added option for mathvec build.
        * configure: Regenerated.
        * mathvec/Depend: New file.
        * mathvec/Makefile: New file.
        * shlib-versions: Added libmvec.

I don't have any comments on the content of this patch beyond that it 
should be combined with patch 6 so that a single patch enables both build 
and install of this library.
