Summary: (expat 1.95.5) 'const' keyword

Initial Comment:
Not all C-compilers knows the 'const' keyword 
(especially old ones). That is why I propse to add the 
following lines into expat.h file:

#ifndef __cplusplus
#define const
#endif

It defines 'const' as empty identifier and everything is 
compiled OK. I attached the diff file for 1.95.5.
Thanks.

Since "const" is ANSI C and additional information has not
been provided, I'm closing this report.

Well, I have to check it out to be sure. I'll post an additional 
info later.

But is xlc the only C compiler for AIX?
A quick google search turned up:

- IBM C for AIX
- VisualAge C++ for AIX
- gcc (version 2.9.aix51.020209 )
- XL C for AIX (seems to have a C89 compliance option)

I seem to recall the xlc compiler on the IBM AIX box.

What C compilers don't support "const"?  That's not exactly a 
recent addition.  Unless you can make the case that there 
are important platforms which can't be supported at all (with 
any compiler) without this, I'll reject it.  It just doesn't make a 
lot of sense to support C implementations that don't comply 
with at least C89.

More exactly, will be better to change it to:

#ifdef XML_NOCONST
#define const
#endif

I guess.
