I'm running cygwin on WinNT 4.0
i repeated your test, i couldn't see any diffs...
i suggest, that it may depend on cygwin env-variable, which _must_ be set before 
starting a new shell!

My cygwin.bat:
@echo off
I:
chdir \cygwin\bin
set CYGWIN=binmode tty ntea nontsec
bash --login -i

The same test as yours:
siebenschlaefer@LORELEY ~
$ stty -a > good

siebenschlaefer@LORELEY ~
$ less good
speed 38400 baud; rows 45; columns 90; line = 0;
intr = ^C; quit = ^\; erase = ^H; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W;
lnext = ^V; flush = ^O; min = 1; time = 0;
