__attribute__(()) perhaps, which is often seen in kernel code.
-fno-gnu-keywords
Do not recognize "typeof" as a keyword, so that code can use this
word as an identifier. You can use the keyword "__typeof__"
instead. -ansi implies -fno-gnu-keywords.
Ergo it's a GNUism/GCCism. As long as <whatever> is used in kernel code,
it should be documented.
