You are absolutely right. I took a look into fcntl.h and there it was.
Apparently my configure script is defining NO_OLDNAMES and not defining
_POSIX. I dunno why. But the _O_BINARY option works just fine and allows
me to avoid the hack with fopen/fileno.
Thanks a bunch. Now I can go ahead and release http://dbh.sf.net 5.0.8 for
windows sometime during the next few days.
