I get the following compile error building cairo-1.8.2 against x.org 6.8.1 (from Fedora Core 4.)

cairo-xlib-surface.c: In function ‘_cairo_xlib_surface_set_attributes’:
cairo-xlib-surface.c:1440: error: ‘RepeatNone’ undeclared (first use in this function)
cairo-xlib-surface.c:1440: error: (Each undeclared identifier is reported only once
cairo-xlib-surface.c:1440: error: for each function it appears in.)
cairo-xlib-surface.c:1443: error: ‘RepeatNormal’ undeclared (first use in this function)

It looks like RepeatNone and RepeatNormal aren't in the older RENDER header file. Hence the build error. The check which turns on and off 
CAIRO_HAS_XLIB_XRENDER_SURFACE probably needs to be tightened up.
