Ops, I thought that O_BINARY is a common, standard thing, but now I see 
that it's only for CRLF'd platforms.

After a quick research, it seems to me that the value of O_BINARY is 
platform specific (and even compiler specific), and in my case (InnoTek 
GCC on OS/2) it's defined to be 0x00020000. However it should be simply 
skipped for platforms where there is no such thing as text and binary 
file, so why not define it to be 0 in cases where it's not defined?
