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.

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.
