The 'refactoring' weenies are trying to produce editors that
automate this sort of global search-and-replace.  I have not tried
any of them yet.  It'd be fairly amazing if they worked well for C++,
let alone C.  (See e.g.

Agreed.  As time goes on, I find incremental refactoring increasingly 
my favorite way to make big changes.
