    Summary:
      Removed all ABS() macros.
    Revision:
      xvidcore--devapi4--1.0--patch-14

    All  ABS   macros  have   been  replace  with   their  stdlib.h/math.h
    equivalent. This gives a 33%  overall speedup for the plain C encoder,
    while the  ia32 one seems to  suffer a small speed  loss. However this
    speed loss is  very small and it  seems it depends on the  CPU type as
    the abs/fabs usage  is impacting badly on sad  functions but impacting
    well on interpolate functions ... weird inst'it ?
