Sounds great to me too; though of course I'd prefer to keep the diff

Oh the other hand, it would be nice if the header guards were
consistently named... and didn't start with an underscore (such
identifiers are supposed to be reserved for the language and/or OS
implementation, unless I am mistaken). Somebody just needs to come up
with a consistent naming style and do it (with some nice script). (The
style of above example would be fine with me.)

  Yes, a script should be enough for this. And yes, "somebody" just needs to do
it :).

otoh, #pragma once is supported by all the compiler we use isn't it ?
so if we are going to change it, why not use that instead.

There are some discussions about that on the Internet. Most interesting: Some kind of benchmark comparison at

http://tinodidriksen.com/2011/08/31/cpp-include-speed/

Looks like header guards as we have them are the best solution on gcc, but the worst for MSVC and no combination would be acceptable compared to 'plain' header guard with gcc.
