Run fixincludeguards.sh on the LibreOffice code base and fix all include guards. I did already fix some dirs, but there's still much to do (sc, connectivity,...). Please mind, that some directories don't have to get converted, like compilerplugins.
find [targetdir] -name *.hxx -or -name *.h | xargs sh fixincludeguards.sh
The script is located at bin/fixincludeguards.sh.
The script was successfully run on the code base. For fixing more include guards, which could be simply identified with fixincludeguards.sh, see Bug 68849.
