This is the name-mangling I mentioned.  C++ does it, but C doesn't.
You could change your asm, but the simplest thing is to change your
C++ header files:

extern "C" {
 extern void SetGrMode (void);
 extern void Draw_Line_Horiz (int X, int Y, int Len, char Col);
 extern void Draw_Line_Vert (long X, long Y, short Len, char Col);
 extern void Draw_Tri (long X1, long Y1, long X2, long Y2, long X3, long Y3,
char Col);
}

AFAIK = as far as I know
IMHO = in my humble opinion
