The current code was written by Thomas. I had the following in an older,
not so elegant patch: (I'm in no way fluent in sed, I need help here):
(indentation modified)

if grep 'define st_dev st_fsid' gen-sysinfo.go >/dev/null 2>&1; then
 grep '^type _stat ' gen-sysinfo.go | \
 sed -i.bak -e 's/st_fsid\([^;]*\)/st_fsid\1; st_dev\1/' gen-sysinfo.go
 grep '^type _stat ' ${OUT} | \
 sed -i.bak -e 's/st_fsid\([^;]*\)/&; st_dev\1/' ${OUT}
fi
