It means that the rest of the C source code is fontified as usual, and 
fontification isn't confused by use of UNINIT.

UNINIT is an attribute for a declarator; it is not an assignment, and should not 
be fontified as an assignment. Although the UNINIT macro might be implemented as 
an '=' followed by an initializer at the low level, this is not always true and 
UNINIT's user should not assume this implementation detail.

Emacs uses lots of other macros for declaration attributes, such as 
ATTRIBUTE_UNUSED and ATTRIBUTE_CONST. These macros all "change syntax" but 
that's acceptable when there is no reasonable alternative using ordinary C 
syntax. So UNINIT is not doing anything unique here; it's got company.
