unnecessary symbol definitions in C++

[David Goodwin <goodwin@xxxxxxxxxxxxx>]

I've looked at this some, but I'm not having any luck fixing it.  sgiCC
generates unnecessary definitions of __FUNCTION__ and
__PRETTY_FUNCTION__. An example that shows this behavior is attached.

WFE_Initialize_Decl claims it ignores unnecessary declarations by checking
DECL_IGNORED_P, but that doesn't seem to work.

main ()
{
  printf("Hello World\n");
}
