Bug in 3.1.2-beta compared with -test1

[Bruce Stephens <B.Stephens@xxxxxxxxx>]

I enclose full details, but briefly, with reasonably sane tty settings, after 
"sleep 1&" returns (or some other background job), some stty settings seem 
wrong: eof, susp, etc., get zapped.  I've never noticed this in previous 
versions.

Here's a difference between zsh-3.1.2-test1 and zsh-3.1.2-beta.  There
seems to be something wrong with tty settings in the latter: they seem
to get corrupted when a background job returns.  I don't find this
happening with 3.1.2-test1.  A possibly relevant difference is that I
compiled 3.1.2-beta with dynamic loading enabled (I was tempted too
much by the stat module) but I've never used that previously (so
3.1.2-test1 didn't have it).  On the other hand, I'm using a pretty
common box: Solaris 2.5.1 with the Sparcworks compiler.

snake% exec zsh -f                                                            ~
snake% echo $ZSH_VERSION
3.1.2-test1
