Details:

A simple Swing testcase suddenly stopped working when I upgraded from
classpath cvs 2005-02-07 to 2005-02-10,



/* Testcase: The window opens only with a probability of about 40%

This seems to be caused by the following change:



http://savannah.gnu.org/cgi-bin/viewcvs/classpath/classpath/gnu/java/awt/peer/gtk/GdkGraphics2D.java.diff?r1=1.29&r2=1.30



Shouldn't GdkGraphics2D not be built at all if cairo is disabled? I don't
know much about configure/auto* stuff myself.
