[webkit-dev] Does ENABLE_XPATH work?

[Paul Pedriana]

If I use '#define ENABLE_XPATH 0' in my config, the build mostly 
compiles, but not entirely. I get the errors shown below. The compile 
errors appear to occur because the code below doesn't check for 
ENABLE(XPATH) (whereas much of the rest of the source code does). Is 
this an oversight, or am I not understanding something about 
ENABLE_XPATH? Note: my build is about five weeks old now, and I admit 
that I don't know how it is that XPATH is used within WebKit.
