# if only this test fails, then configure has guessed incorrectly and
# stty accesses the control terminal from stdout.  The quick fix is
# to edit expect_cf.h and define STTY_READS_STDOUT to 1.  (It should
# be commented out.)  If you figure out a way to fix the configure test,
# let me know.  Else, let me know a way to test for your particular
# machine and os version so it can be hardwired.
