I was not yet ready for review, as I was looking for where it got introduced. Thanks for noticing the missing bug url.

Is the include of V8BindingMacros.h from GenerateNormalAttrSetter() still required?

This is the CL that actually caused the problem:
http://trac.webkit.org/changeset/66521/trunk/WebCore/bindings/scripts/CodeGeneratorV8.pm

I grepped through the generated files, and it seems like the header is never included twice at least.

Sure, but this doesn't mean that we don't add the header to the implIncludes map more than once.

Sorry guys for introducing this.  Could we setup BBs to watch for Android breakage?

[anton muhin]

Just in case: I've added more cases to use the macro.  I hope you already have necessary includes on those paths.

No problem. We'd love to have an Android BB, but we have a lot of upstreaming to do first!

It looks like the macro is only used from ConvertToV8Parameter(), to which this patch adds the include, so I think we're OK.

Anton, do you know if the include from GenerateNormalAttrSetter() can be removed, or are you happy with this patch as it is?

Yes, you're right.  I think it's the best place for inclusion and we don't want to specialize unless build time is prohibitive (which should not be the case, hopefully)
