Small patch to fix AIX compile
Jason,
This is necessary to avoid compilation errors using xlC on AIX. Note that
I'm not sure how to convince swig to generate this in the first place!
I've used swig in the past, but always found it more painful than direct
XS coding so I'm not up on the nitpicky details anymore.

XS(_wrap_new_MemBufInputSource) {
XMLByte *arg1 ;

char *arg3 ;
bool arg4 = false ;
int argvi = 0;

XS(_wrap_new_MemBufInputSource) {
XMLByte *arg1 ;
! STRLEN arg2 ;
char *arg3 ;
bool arg4 = false ;
int argvi = 0;
I never did make any progress in getting an AIX build to pass all the
tests. So far I've tried xlC 3.6.6, VAC++ latest and the so-called "linux
affinity" g++ for AIX 4.3.3. The xlC build comes the closest to working,
but exception propagation is quite broken for some of the tests. VAC++
just gives the same result. g++ is hopeless (module segfaults immediately
on load) and would probably require a Perl built with gcc (mine are all
built with xlc), as the standard AIX build uses loadAndInit() to perform
static initialization of C++ constructs - failing miserably against g++
object output.
As soon as I figure out how to use the new idebug debugger, I'll try again
to trace the problem. xldb seems to have serious problems following the
threading...

In this case it should be as hard as:
* downloading SWIG-1.3.10 from www.swig.org
* installing it somewhere in your path
* export XERCES_DEVEL=1
* re-run 'perl Makefile.PL' and you should see a 'Welcome Xerces
Developer!' output line
* modify Xerces.i, postModule.pl, or postSource.pl
* make
I've done all the nasty work in
* Xerces.i: all the SWIG mappings
* postModule.pl: perl script to modify Xerces.pm after SWIG is done
* postSource.pl: perl script to modify Xerces.C after SWIG is done
In this case, you'd have to add something to postSource.pl.

Hmm... That's irritating that it can't cast this automatically. I'd
like to get a Xerces.C file that works on all architectures, so I
wonder if Linux will handle the STRLEN, if so I'll change it.

Wow. Thanks for the dedication! I'm not going to have much Xerces time
in the next couple of weeks, but please keep posting your results, and
I'll do what I can to help.
jas.
