    * gdb.base/a1-selftest.exp: Reset the timeout value to 30 seconds
        after the inferior gdb has started.
'cuz lynx may take a couple minutes to start the inferior gdb...

        * gdb.base/a2-run.exp: Handle gdb echoing more than one cr-lf
        after each command.
        * gdb.base/funcargs.exp: Likewise.
        * gdb.base/gdbvars.exp: Likewise.
        * gdb.base/interrupt.exp: Likewise.

Just in case we can't get a version of expect that sets the tty modes
right on lynx to avoid this problem.
