+commit 95f6f7a174ca096a3d3dbe84ff220d166d1e2baa
+Author: Uli Schlachter <psychon@znc.in>
+Date:   Fri Oct 22 11:54:57 2010 +0200
+
+    Make both versions of _cairo_lround consistent again
+    
+    Commit c0008242b0f made cairo use libm's lround instead of its own _cairo_lround
+    by default. However, since commit ce58f874 from 2006, _cairo_lround does
+    arithmetic rounding instead of away-from-zero rounding (before said commit, it
+    was using baker's rounding).
+    
+    So to make the rounding of _cairo_lround be independent from
+    DISABLE_SOME_FLOATING_POINT, we have to use another function. Turns out that
+    _cairo_round already does the same thing that _cairo_lround does. Their only
+    difference is the return type.
+
