Todays kdelibs/kdoctools build is broken because of the use of LIBXSLT_PUBLIC 
defines in xlstInternal.h which is not defined in our build tree. One fix is 
to #define LIBXSLT_PUBLIC before including the files. Is this the right way 
to solve the problem?

The files needing the hack are main.cpp and kio_help.cpp.

Rich.
