Alternatively, the call:

  _binmode(1);

somewhere at the beginning of a program will cause all fopen()s to
default to binary mode (you can then force text mode with the "t"
modifier in the mode specifier.)  It's much easier, (and cleaner,
IMHO) to make this one small hack than to hunt down all the file mode
arguments all over a large program.
