It's taking me about 7 seconds, on an Emacs version whose latest applied
revision is 116070.

Quick update to current (latest revision 116146), and rebuild .......

It's still taking me about 7 seconds.  As far as I can see, you haven't
installed your temporary patch to syntax.c.  So, I haven't been able to
reproduce the problem yet.

Is there something more subtle I'm missing?

[P.S. isn't it good that we can use revision numbers to identify
approximate ages of repository states. ;-]
