/* 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.*/ #if defined(__GNUC__) && defined(__i386__)/* We'll use this version by default only where we know it helps.    regparm() generates warnings on Solaris boxes.
