I don't think there's anything wrong with the original version except that
there is a lowercase 'o' where the zero should be (in main's return statement.)
 

cd c:/elc/djgpp/works/tester/pipechar/
gcc -Wall pipechar.c
pipechar.c: In function `main':
pipechar.c:5: `o' undeclared (first use this function)
pipechar.c:5: (Each undeclared identifier is reported only once
pipechar.c:5: for each function it appears in.)
pipechar.c:7: warning: control reaches end of non-void function

Compilation exited abnormally with code 1 at Sun Sep  6 19:02:53
-----------------
...then after changing the 'o' to '0':

cd c:/elc/djgpp/works/tester/pipechar/
gcc -Wall pipechar.c

Compilation finished at Sun Sep  6 19:03:46
