I just installed the latest djgpp C compiler on my Windows 98 machine,
and I cannot make this simple program  work correctly.  It is supposed
to simply open a file and write out 5 bytes.  It does work correctly
(without any changes) on Linux.  The Windows version always inserts a
0x0d before every 0x0a.  On Windows my output file ("junkfile") has a
total of 7 bytes ( two 0x0d bytes added), but on Linux my output file
has a total of 5 bytes, as expected.

/*-------------------- START OF PROGRAM --------------------*/
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <fcntl.h>

int main() {

   char myfile[] = "junkfile";

   int out;
   char buf[100];

   if ((out = open(myfile, O_CREAT | O_WRONLY )) < 0 ) {
      perror(myfile);
      exit(1);
   }

   buf[0] = 0x61;
   buf[1] = 0x0a;
   buf[2] = 0x62;
   buf[3] = 0x0a;
   buf[4] = 0x63;

   write(out, buf, 5);

   close(out);
   exit(0);

}

Thanks for any and all help!
