Well, I'm going out on a limb here, because I'm really not familiar with
the Cygwin package, but if it makes a distinction between writing to
binary files vs. text files, adding CRs before LFs on text files, then this
could be the problem here. htdig/ creates its temporary
file using:

    FILE *fl = fopen(path, "w");

If this causes the Cygwin library to do CR/LF expansion, you'd need to
change this to avoid that problem, e.g. by using "wb" as the second
argument, if that's what it takes, or somehow setting O_BINARY mode on
the file. Have a look at the Cygwin docs, and please let us know if you
find a fix - we'll try to incorporate a portable form of it in future
