Failed compilation with STLPort 4.5 - attributed to operator==

Xalan 1.2 fails to compile with STLPort 4.5 under i686 GNU/Linux gcc-2.95.2.
Numerous files fail, including XSLT/VariableStack.cpp, XSLT/Stylesheet.cpp,
XercesParserLiason/XercesParserLiason.cpp.

Each compilation problem seems to arise from the use of non-member operator==
functions in a number of classes within files in the XPATH directory. By
changing these to member functions the problem goes away. Pretty wierd, huh?

I've confirmed that everything's fine with STLPort 4.0. It also seems to be OK
with Solaris 8 & gcc-2.95.2

e.g.

Changing operator==(const XObject& theLHS, const XObject& theRHS) in
XPath/XObject.hpp

to a member function:

bool operator==(const XObject& theRHS) const

seems to work (if you also remove the friend declaration!)
