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