In order to support obtaining the line and column locations of problems in
XML files, we are now using Python 2.4's version of the 'pyexpat' module,
built as 'peak.util.pyexpat'.  Also, added "empty" option to negotiating
XML parser, so that tags which don't want any children can force an error
if a child element appears within them.
/* internal.h

   Internal definitions used by Expat.  This is not needed to compile
   client code.

   The following calling convention macros are defined for frequently
   called functions:

   FASTCALL    - Used for those internal functions that have a simple
                 body and a low number of arguments and local variables.

   PTRCALL     - Used for functions called though function pointers.

   PTRFASTCALL - Like PTRCALL, but for low number of arguments.

   inline      - Used for selected internal functions for which inlining
                 may improve performance on some platforms.

   Note: Use of these macros is based on judgement, not hard rules,
         and therefore subject to change.

/* We'll use this version by default only where we know it helps.

   regparm() generates warnings on Solaris boxes.   See SF bug #692878.

   Instability reported with egcs on a RedHat Linux 7.3.
   Let's comment out:
   #define FASTCALL __attribute__((stdcall, regparm(3)))
   and let's try this:
*/
#define FASTCALL __attribute__((regparm(3)))
#define PTRFASTCALL __attribute__((regparm(3)))
#endif

/* Using __fastcall seems to have an unexpected negative effect under
   MS VC++, especially for function pointers, so we won't use it for
   now on that platform. It may be reconsidered for a future release
   if it can be made more effective.
   Likely reason: __fastcall on Windows is like stdcall, therefore
   the compiler cannot perform stack optimizations for call clusters.

/* Make sure all of these are defined if they aren't already. */
