Thanks! I fiddled with this a bit more, to centralize more of the
platform-dependent stuff to RewindTest.pm. Also, Windows doesn't have
"cat" and "touch" if you haven't installed MinGW, so I replaced those
calls with built-in perl code.

Can you double-check that the attached still works in your environment?
It works for me now.

Note: I had some trouble installing IPC::Run on my system, with
ActiveState Perl and MSVC. There is no PPM package of that for Windows,
so I had to do "cpan install IPC::Run". That downloaded the MinGW C
compiler and make utility, which took a while. But some of the IPC::Run
regression tests failed, and the installation was aborted. I forced my
way through that "notest install IPC::Run". The next obstacle was that
"vcregress <anything>" no longer worked. It complained about finding
some function in the Install module. Turns out that when it installed
the C compiler and make utility, it also installed a module called
"install" from cpan, which has the same name as the PostgreSQL
Install.pm module. We really should rename our module. I got through
that by manually removing the system install.pm module from the perl
installation's site directory. But after that, it worked great :-).

We need to put some instructions in the docs on how to install IPC::Run
on Windows. I can write up something unless you're eager to.
