Re: [PATCH] RDOS support for newlib

Leif,

A number of issues.

1. Files from the top-level directory require special approval since
   these files are shared with other projects.  See the
   top-level MAINTAINERS file for details on which mailing
   lists to send various patches to.

2. You have patches to generated files (configure, aclocal.m4).
   You must only provide patches for the files that generate these and
   do not post the generated diffs.

3. You make libtool changes.  Do you intend on using libtool to
   build rdos under newlib?  There is more involved in this.

Note the code below that only allows libtool for x86-linux:

case "${host}" in
  i[34567]86-pc-linux-*)
    use_libtool=yes
    have_sys_mach_dir=yes
    stdio64_dir=stdio64
    oext=lo
    aext=la ;;
  *) ;; #shared library not supported for ${host}
esac

4. You must submit the initial patch for your new files.  You may
   request to be the maintainer of said files once they are
   approved and to check-in patches without prior permission, but
   that right is never given to anyone sight-unseen and may
   require a few patches to build up a trust factor.

I enclose request for patches and changelog for RDOS
support in newlib.

I don't include the required files in newlib/libc/sys/rdos.
I would like to add and maintain these files myself.
