[Expectperl-discuss] Warnings with latest Expect and IO::Tty/Pty

[Stephen <S.J...@du...>]

I have just compiled and installed IO::Tty/Pty version 1.01 and Expect
1.15 on my Solaris 8 box, details here:

SunOS duss0 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-250

everything compiles, installs, passes the tests and runs which is great! 
Glad to see things working again after some difficulties i've had with the
recent earlier versions of IO::Tty/Pty. I am however getting a couple of
warnings, not sure if they are important or not but they are a little
annoying. They are: 

Use of uninitialized value at
/loc/lepus/dph3sjq/perl/sun4-solaris/IO/Tty.pm line 19.

Use of uninitialized value at
/loc/lepus/dph3sjq/perl/sun4-solaris/IO/Pty.pm line 16.

These refer to the lines in the two modules which both say:

eval { undef local $SIG{__DIE__}; local $^W = 0; require IO::Stty };

My perl version details are:
