+/* 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.

+/* 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.
