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