So apparently
using a particular zip program wasn't the issue, you only didn't want to
install one?
In that case, you could as well have used the one from
MSYS zip or the one from
UnxUtils or
GnuWin zip, or even ye goode olde infozip if you still find it somewhere.
They're all the same (well, not quite, but the result is the same).
As for running Subversion, you can skip this if you can live with the "Start Here" page showing revision 0. It has no other bearing. And if this annoys you, then you can edit
trunk/src/include/autorevision.h by hand, entering the correct number (which you hopefully remember) in both places, and the date you checked out. Then you'll even have the right revision number showing.
