Is this really SPI everywhere? I think at least on OS X, this file is API.

I don't think you are including a header for this. It is defined in bootstrap_priv.h,

Why not just make DumpRenderTree get it from WebKit2?

You're right! Will fix as this is API on OS X.

Will include header bootstrap_priv.h when building with the Apple Internal SDK.

I can do this. When I wrote the patch I thought it would be considered bad form to have a WebKit1-based application, DumpRenderTree, depend on a WebKit2 header and I did not want to add to the bad practices used by DumpRenderTree (including referencing headers from WebCore).

I know this is the title of the bug, but the patch actually makes DumpRenderTree build.  Maybe better to change "WebKit2" to "DumpRenderTree"?

Not to be pedantic, but do these need to be named WTF_EXTERN_C_BEGIN and WTF_EXTERN_C_END so we don't conflict with someone else's headers?

This was moved to a different patch, I think.

No, more build fixes are needed to make DumpRenderTree build with the public SDK.

Will rename EXTERN_C_BEGIN and EXTERN_C_END to WTF_EXTERN_C_BEGIN and WTF_EXTERN_C_END, respectively.
