<pre>Building cairo with 'clang' there is an interesting warning:
<span class="quote">>path-precision.c:43:17: warning: implicit conversion from 'double' to 'int' changes value from 41.25581 to 41 [-Wliteral-conversion]

Adding a '.point = ' between the two open braces in the lines specified
in clang output and at line 40 makes the test log change from:
<span class="quote">>Testing path-precision with image target (dev offset 0 scale: 1)
>Paths differ in coordinates after 0 operations.
>Expected point (0.000000, 0.000000), found (0.000000, 0.000000).
>Error: Function under test failed
>TEST: path-precision TARGET: image FORMAT: rgb24 OFFSET: 0 SCALE: 1 SIMILAR: 0 RESULT: XFAIL</span >
to:
<span class="quote">>Testing path-precision with image target (dev offset 0 scale: 1)
>Paths differ in coordinates after 1 operations.
>Expected point (94.960533, 41.255810), found (94.960938, 41.253906).
>Error: Function under test failed
>TEST: path-precision TARGET: image FORMAT: rgb24 OFFSET: 0 SCALE: 1 SIMILAR: 0 RESULT: XFAIL</span >
which seems to be a little more similar to the input and to the
expectations.</pre>
