I'd leave it alone, not only on the general principle of laziness,
but also because (unless they've ripped out the code I contributed
many years ago) GCC optimizes away "#include <foo.h>" if foo.h's
contents are protected in that way and the change will let GCC
run measurably faster if the file is included multiple times.
