+ 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.
