  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.
