I'm trying to use the DJGPP port of GNU sort with the "-u" option to
eliminate all but one equal-key record.  However, all I ever get is a
single record output, the first record in the file.

Is this a known problem with the DJGPP port, or am I not using sort
correctly?

TIA for any help or info you can provide.  Sample data and command
follow.

============= sortuniq.tst =============================
field1\tfield2\tfield3 9 field3\tfield4\tfield5\tfield6/9\tfield7
field1\tfield2\tfield3 1 field3\tfield4\tfield5\tfield6/1\tfield7
field1\tfield2\tfield3 2 field3\tfield4\tfield5\tfield6/2\tfield7
field1\tfield2\tfield3 3 field3\tfield4\tfield5\tfield6/3\tfield7
field1\tfield2\tfield3 4 field3\tfield4\tfield5\tfield6/4\tfield7
field1\tfield2\tfield3 5 field3\tfield4\tfield5\tfield6/5\tfield7
field1\tfield2\tfield3 6 field3\tfield4\tfield5\tfield6/6\tfield7
field1\tfield2\tfield3 7 field3\tfield4\tfield5\tfield6/7\tfield7
field1\tfield2\tfield3 8 field3\tfield4\tfield5\tfield6/8\tfield7
field1\tfield2\tfield3 1 field3\tfield4\tfield5\tfield6/1\tfield7
============= sortuniq.tst =============================
[Replace all "\t" with a real tab before using]

Command and sample output used to sort on fields 3 and 6 with -u, tab
specified as field separator:

C:\stest>sort +2 +5 -t \t -u sortuniq.tst
field1  field2  field3 9 field3 field4  field5  field6/9        field7
