Description

Hey,

I've had a large number bug reports in Xerces-P for the 2.3.0 release related to
linking errors with isAnySlash(). For OS X the problems was eliminated by
removing the 'inline' directive from the .cpp file and recompiling. For Redhat
Linux this did not help, and Xerces-P was forced to remove the method from the
API to enable linking.

I'm at a loss to figure out why this one method should create problems on two
such different platforms. The linux user was using an old version of gcc (2.96),
so perhaps this is an issue?

Yes, all the xerces-c sample programs run fine.

Here's what I get:

1. nm -C /usr/local/xerces-c-src_2_3_0/lib/libxerces-c.so | grep -i isanyslash

1. nm -C
2. /usr/local/src/perl/XML-Xerces-2.3.0-1/blib/arch/auto/XML/Xerces/Xerces.so

3. grep -i isanyslash 0005de34 T _wrap_XMLPlatformUtils_isAnySlash U xercesc_2_3::XMLPlatformUtils::isAnySlash(unsigned short)

So, I guess the error message is correct in reporting that the symbol is
undefined. I'm in a little over my head with all this compiler/linking
stuff though. How can I fix this?
