I think that there is a bug in `sort' program.  It *sometimes*
ignores new style key options (usually during first invocation).
I obtained the same results on two different machines.  I can't
check whether it is something specific to DJGPP or GNU-wide sort
bug.  Could someone with access to UNIX GNU sort program test it?

Here is my session script:

D:\USER>cat a              <- example file
e c
a d
b e
c a
d b

D:\USER>sort -k 2,2 a      <- sort by second column, new option style
a d                        <- wrong answer, sorted by first column
b e
c a
d b
e c

D:\USER>sort +1 -2 a       <- sort by second column, old option style
c a                        <- correct answer
d b
e c
a d
b e

D:\USER>sort -k 2,2 a      <- again new option style
c a                        <- now correct answer!
d b
e c
a d
b e

D:\USER>sort --version
sort - GNU textutils-1.19
