I removed everything that was not necessary to show the problems. I do not
bother typos :)

- You are defining "void main", despite this you return an exit
code with the exit() function.

- You check for argc==1, but you do not stop the program in this case. Now,
assume argv[argc]==NULL. Ansi guarantees this, but what does it mean when
you call

spawnvp(...,NULL,...)?


Tschau...Thomas
