Yes, indeed. In a nutshell, "gnu" style imposes a minimum indentation of
1 from column zero.
In more detail, it's in the CC Mode manual, as follows:
(i) Your CC Mode "style" is "gnu" (the default, since you haven't changed
it). Styles are explained on the pages "Config Basics" and "Styles".
(ii) "gnu" style imposes a minimum indentation of 1 character FROM COLUMN
ZERO. This is to help source code utilities which search for things in
column zero. This "1 character" is in user option
`c-label-minimum-indentation' which is on page "Other Indentation".
You can fix this either by setting the default style to something other
than "gnu" (user option `c-default-style' on manual page "Choosing a
Style"), or by setting `c-label-minimum-indentation' to zero.
As a matter of interest, why are you typing an if-statement in column
zero? :-)
