DOS text files use a CR/LF combination to designate the end of a line,
while Unix text files use only a CR.  Thus, DOS text files are larger
than the corresponding Unix file.  For this reason, you should NEVER
open a text file in binary mode.

There are utilities in the DJGPP distribution called 'dtou' and 'utod'
that can convert between DOS and Unix style text files.
