    nautilus-global-preferences: use 'extern' properly
    
    Variables in header files should have 'extern' on them and be defined
    from a single .c file, otherwise you get a copy of the variable every
    time you #include the header.
    
    -fcommon masks this problem, but building with -fno-common fails because
    of it.
