/Users/crschmidt/webkit/WebKit/WebCoreSupport.subproj/WebImageRenderer.m: In function `-
[WebInternalImage _PDFDrawFromRect:toRect:operation:alpha:flipped:]':
/Users/crschmidt/webkit/WebKit/WebCoreSupport.subproj/WebImageRenderer.m:956: warning: 
`NSGraphicsContext' may not respond to `-setCompositingOperation:'
/Users/crschmidt/webkit/WebKit/WebCoreSupport.subproj/WebImageRenderer.m:956: warning: cannot 
find method `-setCompositingOperation:'; return type `id' assumed

(void)setCompositingOperation:(NSCompositingOperation)operation;
(NSCompositingOperation)compositingOperation;

Function is new in 10.4.

Compiling without -Werror does allow the build to continue.

Removing -Werror from the build line in the Terminal does not work for me. I get the same error for the 
missing setCompositingOperation method.

We won't support building under 10.3.9 ever again. Sorry. Closing as WONTFIX.
