    45	/* Expat tries very hard to make the API boundary very specifically
    46	   defined.  There are two macros defined to control this boundary;
    47	   each of these can be defined before including this header to
    48	   achieve some different behavior, but doing so it not recommended or
    49	   tested frequently.
    50	
    51	   XMLCALL    - The calling convention to use for all calls across the
    52	                "library boundary."  This will default to cdecl, and
    53	                try really hard to tell the compiler that's what we
    54	                want.
    55	
    56	   XMLIMPORT  - Whatever magic is needed to note that a function is
    57	                to be imported from a dynamically loaded library
    58	                (.dll, .so, or .sl, depending on your platform).
    59	
    60	   The XMLCALL macro was added in Expat 1.95.7.  The only one which is
    61	   expected to be directly useful in client code is XMLCALL.
    62	
    63	   Note that on at least some Unix versions, the Expat library must be
    64	   compiled with the cdecl calling convention as the default since
    65	   system headers may assume the cdecl convention.
