local.h is just a local header file that is not externalized.  It is also not 
meant to be included multiple times.  The C header files available to the 
end-user have to be protected from multiple inclusion as some header files 
include others and the end-user is not restricted from including them multiple 
times.  This is not the case for local.h.

I have removed the extraneous 2nd include.  Thanks for spotting this.
