On a clean login, I get,

And after "stty sane":

brkint -inpck -istrip icrnl -ixany imaxbel onlcr
echo echoe echok echoctl echoke iexten

pedro@opensolaris:~/orlando/gdb/multi_process/build-solaris/gdb$ /usr/bin/stty -a
speed 38400 baud;
rows = 30; columns = 80; ypixels = 0; xpixels = 0;
csdata ?
eucw 1:0:0:0, scrw 1:0:0:0

Sorry, I may have mixed up what I showed, because I only learned after
the fact that "stty" != "stty sane".  :-)

Here's a diff of what you see after stty sane, and what I see after stty sane.
The ">" version is yours:

I then went through the all the options I had used in the workaround,
and identified that it is setting onocr that makes the "\r\r\n" go away.

I'm now working around this by replacing /usr/bin/stty by:

 #!/bin/sh

 if [ $# == 1 ] && [ x"$1" == xsane ]
 then
     exec /usr/bin/stty.org $* onocr
 else
     exec /usr/bin/stty.org $*
 fi

The gdb.mi tests all fail because all commands that GDB sends
are echoed back :-(.  If I remove the onocr, the GDB commands are
not output at all.  :-(
MI testing is not important for me, though, so I consider
it a victory that I'm able to test at all...
