[Nel] ugh, C++ is so obtuse

[robert@paradox.got.net]

Building latest CVS I get the following:

client.cpp:433: cannot declare variable `ChatDisplayer' to be of type `CChatDisplayer'
client.cpp:433:   since the following virtual functions are abstract:
/usr/local/include/nel/misc/displayer.h:62:     void NLMISC::IDisplayer::doDisplay(long int, NLMISC::CLog::TLogType, const _STL::string &, const char *, int, const char *)

Anybody else getting this?  I'll figure it out myself if I'm the only
one,  Otherwise I'd prefer to let someone who knows C++ deal with it.

Robert
