The warning is appropriately conditioned on whether you're in C99 mode.  
If you use -std=c99 or -std=gnu99 you won't get the warning (but Linux
uses at least one feature only permitted in gnu89 mode, treating compound
literals as values that can be used in static initializers rather than
references to anonymous variables which is the C99 notion).
