Then perhaps you would consider the patch below. It addresses the 
'empty declaration' warnings generated when compiling Bash and 
other packages. Other headers would need adjustment too, of course. 
Instead of defining the  __DJ_* macros to null after first use, it 
undefines them so the '#if defined' test, when applied to other headers 
using the __DJ_* macros, avoids defining a type twice and generating 
a warning about an empty declaration.
