-------------------------------------------

Some question :
1. Why do _both 'gcc -v' and 'gpp -v'_ produce the same output?
2. What is GNU CPP version ... ? (C compiler?)
3. 'gpp -v a.c' produces _C++ compiler_ version as well.
   Why doesn't 'gpp -v' do the same thing?
4. Is there any option that produces _C++ compiler_ version ? :
   %gpp <?-option>
   GNU C++ version 2.95.3 20010315/djgpp (release) (djgpp) compiled by
GNU C version 2.95.3 20010315/djgpp (release).
