The original file is a dos format text file. Dos text files have CR-LF
at the end of every line, whereas unix files only have LF. The extra CR
is the ^M you're seeing. Obviously awk (mawk?) is not handling the text
format properly, instead assuming it is a unix format file. Your belief
that the original file does not have ^Ms is incorrect. It does have
them, but they just don't show up on most editors. If you edit it with
nvi, you'll see them there.
I'd suggest one of two things:
1. If your awk is mawk, try installing gawk (GNU awk) and see if that
handles dos text files better.
2. Convert the files by removing the ^Ms before running awk on them.
This is basically a compatibility problem, not a bug in awk.
