I understand your intention, but I'm not really happy with it.

So far, the version_string is mostly architecture and system independent.
I haven't seen any comments about this, but I can imagine that we want
such information globally.

On the other hand, that would require changes to many files, and the
gcc __VERSION__ string is pretty long on some systems, which may cause
additional problems.

I also doubt that we need this information with each boot message
(where it just slows down booting).

Would it not be sufficient to add this to the code of do_version() so
we can get this information when we want it, i. e. when running the
"version" command?

Best regards,

Wolfgang Denk
