// 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().
//
//####DESCRIPTIONEND####
