I've attached modified chartinfo.h (and a made up chartinfo.cpp) to 
illustrate how you can work around the problem you've encountered using 
a forward declaration.  You have to make sure you include s_57_defs.h 
only once, in a C/C++ source file (not header) so that you wouldn't have 
multiply defined global variables.
