I'd bet that the source file is in DOS format (ie., it has '\r\n' line
endings instead of '\n'), and that's what's causing the problem. To
check, do the following:
  
  $ od -c test.cpp | less

if you see '\r' there, that's your problem. If so, use recode or some
such program (or, in vim, do a ``:set ff=unix'' and then write it out)
to get rid of the '\r' and you should be set.
