svn-apply seems to be having trouble with the "adds" for the WTF
files, thus causing all the EWS bots to fail.

I'm also working on getting a git branch (on github) of my changes, to
make it easier for port maintainers to send me updates (instead of
passing around 5MB diffs).

At this point it may be best to just land the change tomorrow and fix
all the buildbots after the fact.  We should be very close, with all
the header work which has been done over the last month.
