It would be safer to add the compiler flag indeed, as we are including files
from mm/ in vma.c here, so if some change in mm/ files makes them rely on
syntax permitted only gnu11, we'd break the compilation of the test.

Also please update the commit log to talk about function definitions and not
function declarations, as that turned out to be the important detail. Thanks!
