        * Makefile.am:  Add i_cshift1a_c.  Add rules to generate files
        from cshift1a.m4.
        * Makefile.in: Regenerated.
        * m4/cshift1a.m4: New file.
        * m4/cshift.m4 (cshift1): Split up inner loop by removing
        condition. Use memcpy where possible.  Call helper functions
        based on dtype.
