Globally setting c-basic-offset overrides the cc-mode style inheritance
system.  There are various ways to customise this variable in a more
granular way, such as defining a custom style which inherits from a
built-in style, or setting c-basic-offset locally in a mode hook.
For details, see (info "(ccmode) Config Basics").
