As there have been a question about how to write an makefile with 
auto-dependencies and more questions about linking-problems using 
pure-virtual functions I've extracted an example including both.

The files are class_a.h, class_a.cc, class_b.h, class_b.cc, class_c.h, 
class_c.cc, main.cc and the makefile. One known problem with the 
autodependencies is mentioned in the makefile. 

The example compiles and runs fine on my machine (486/66DX2, 32M RAM, 
DOS6.2 with HIMEM and EMM386) using djgpp 1.12m4.

Hope this helps,
  Roland
