Well, and exactly this is valuable information which should be
included into the commit message.

Indeed, neither __func__ nor __FUNCTION__ can be concatenated; for
some reason gcc seems to consider these as strings, but not as string
constants. Dunno why; probably there is a good reason for this, but
it looks stupid to me.

Best regards,
