/* 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. __ __ _ ___\ \/ /_ __ __ _| |_ / _ \\ /| '_ \ / _` | __| | __// \| |_) | (_| | |_ \___/_/\_\ .__/ \__,_|\__| |_| XML parser Copyright (c) 2002-2003 Fred L.
