You might as well check out the current development version of dtou.c
and utod.c via the anonymous CVS access on DJ's server (see
http://www.delorie.com/djgpp/cvs.html for the details).  Andris
Pavenis just submitted patches to make these programs compile and work
on Unix/Linux systems.

The usual way is to define O_BINARY to zero, if it isn't defined by
fcntl.h, then use it as in "O_RDONLY | O_BINARY".

Lone CRs should be preserved, otherwise programs which have buffers
with literal unprintable characters will be corrupted.

You could always use chown to preserve the owner as well, but that
will sometimes fail.
