[Mingw-msys] Defferences between MSYS and GNUWin32 sed's

[Neil M. <Nei...@of...>]

I hope a good answer to this question will help clarify my ongoing confusio=
n about MSYS, MinGW and GNUWin32.

I have a script that uses both sed and then tac (cat backwards, reverses a =
file) and I noticed a difference in the size of the resulting files. The se=
d is the MSYS sed, but as tac is not part of MSYS I got it from another sou=
rce.=20

The difference in the size of the files produced is in the line endings.  T=
he file produced by MSYS sed is smaller, emacs reports it as type 'Unix' an=
d it does not display properly in notepad. The file produced by tac is larg=
er, emacs does _not_ report it as type 'Unix', and it is displayed properly=
 in notepad.

As I'm on windows I'm inclined to use the larger format and am wondering if=
 the GNUWin32 sed will produce that larger format. That leads me to wonder =
about why the MSYS sed is different to the GNUWin32 sed and from there back=
 to my confusion about MSYS, MinGW and GNUWin32.

Anyone care to clarify why there is a MSYS and GNUWin32 sed and the differe=
nces between them?

TIA,
Neil (J Mackie).
