Re: sh: -c: option requires an argument on Cygwin

[Diomidis Spinellis]

I cannot replicate the problem in Cygwin 0.8.1

$ parallel -k echo ::: A B C
parallel: Warning: $SHELL not set. Using /bin/sh.
A
B
C
$ SHELL=/bin/bash parallel -k echo ::: A B C
A
B
C
$ SHELL=/bin/sh parallel -k echo ::: A B C
A
B
C

Could you be using a non-standard shell or an older version of Cygwin?
