Follow-up Comment #6:

I think the %!test code has simply been too naive in assuming that on a PC
platform the sort routine will be that provided by Microsoft.  It might, or it
might not be, and this could depend entirely on the local setup.  In my case,
I have a third variant in that I have manually installed a number of GNU utils
using downloadable installers.  So I don't have MinGW installed, and we could
remove sort.exe from <OCTAVE_HOME>/bin, and yet I would still be getting a
UNIX-like sort program on the command line.

This is pretty easy to test for.  I tried


status = system ("sort.exe --help");


which returns a non-zero value when sort is the Microsoft version. 
Alternatively,


status = system ("sort.exe /?");


will return a non-zero value when sort is a UNIX-like version.  It's only a
single %!test so it might look kind of ugly to check the sort routine, but
there isn't any performance penalty.  What do you think?
