//#####DESCRIPTIONBEGIN####
//
// Author(s):   bartv
// Date:        2003-03-27
// Purpose:     provide a __cxa_pure_virtual() function
// Description: g++ v3.x generates references to a function __cxa_pure_virtual()
//              whenever the code contains pure virtual functions. This is a
//              placeholder used while constructing an object, and the function
//              should never actually get called. There is a default
//              implementation in libsupc++ but that has dependencies on I/O
//              and so on, unwanted in a minimal eCos environment. Instead we
//              want a minimal __cxa_pure_virtual().
