Comment(by kyngchaos):

 There are more places in Qgis that use abs().  Maybe should be changed for
 consistency?  After r14711 I found:

  * core/composer/qgscomposeritem.cpp
  * core/qgscoordinatereferencesystem.cpp
  * core/qgsmaprender.cpp (acually fabs())
  * core/qgspoint.cpp (right above changes made in r14711)
  * core/spatialindex/geometry/LineSegment.cc (though this seems to be
 independent of Qt/Qgis)
  * core/spatialindex/rtree/Node.cc (same as previous)
  * gui/qgsannotationitem.cpp
  * plugins/georeferencer/qgsgeoreftransform.cpp
  * plugin/grass/qgsgrassselect.cpp
  * plugin/grass/qtermwidget/TerminalDisplay.cpp

 For older OS X versions, if it's in Qt I think it should be OK.  I can
 test back to 10.5 only.  Qt "official" binaries support back to 10.4, but
 the C++ version is almost identical to 10.5 (4.0.x), if that means
 anything.
