You can replace all this with simply:
    FontDatabase::singletonAllowingUserInstalledFonts().clear();
    FontDatabase::singletonDisallowingUserInstalledFonts().clear();

without ifdefs. FontDatabase::singletonAllowingUserInstalledFonts() & FontDatabase::singletonDisallowingUserInstalledFonts() resolve to FontDatabase::singleton() when !HAVE(DISALLOWABLE_USER_INSTALLED_FONTS)
