Getting Formatting Errors Loading .C Files in Turbo C for DOS

In the MS-DOS era, non-Unix systems that used a bare carriage return as a newline were more common than non-Unix systems that treated a linefeed in such fashion. Consequently, many programs including Turbo C would accept text files where newlines were indicated as bare carriage returns, but choke on files where they were indicated with bare linefeeds. It should be simple to write a program that will open a file in binary mode for reading and another for writing, reach each byte of the former, and implement a simple state machine that would ignore any carriage return that followed a linefeed that was not ignored, or any line feed that followed a carriage return that was not ignored, output a CR+LF pair for any linefeed or carriage return that was not ignored, gobble any byte 0x1A and ignore everything after it, and otherwise pass input data through unmodified. Such a program would convert all of the line endings in a file to MS-DOS format.
