The problem doesn't occur on DOS.  It occurs on Unix, when you use DOS
files without converting them to Unix format.  In general, if you want
to use a DOS-format text file on Unix, you need to remove trailing CR;
lots of tools break if you don't, and in some cases POSIX requires
them to break.

Recent versions of GCC accept either LF, CR LF, CR, or LF CR as line
ends, so you shouldn't have a problem with them even if you have
messed-up files like that.  (POSIX allows this extension, I think.)
However, you'll still have a problem if you use unconverted text files
from unusual operating systems like S/390, as they use line-end
conventions that are not in GCC's list.
