11/* Expat tries very hard to make the API boundary very specifically
12   defined.  There are two macros defined to control this boundary;
13   each of these can be defined before including this header to
14   achieve some different behavior, but doing so it not recommended or
15   tested frequently.
16
17   XMLCALL    - The calling convention to use for all calls across the
18                "library boundary."  This will default to cdecl, and
19                try really hard to tell the compiler that's what we
20                want.
21
22   XMLIMPORT  - Whatever magic is needed to note that a function is
23                to be imported from a dynamically loaded library
24                (.dll, .so, or .sl, depending on your platform).
25
26   The XMLCALL macro was added in Expat 1.95.7.  The only one which is
27   expected to be directly useful in client code is XMLCALL.
28
29   Note that on at least some Unix versions, the Expat library must be
30   compiled with the cdecl calling convention as the default since
31   system headers may assume the cdecl convention.
