build-svn-deps-win.pl and debug builds

It would be interesting if build-svn-deps-win.pl could also build
debug builds of the dependencies (so I can use them to make a debug
build of svn).

I suppose this is basically using "Debug" throughout the file where it
currently says "Release", and installd instead of installr for httpd
etc. [1]

Now I went through the necessary steps manually, but in retrospect it
would have been better if I had spent some time editing the
build-svn-deps-win.pl script.

Does anyone have a patch lying around for that (or can whip one up in
5 minutes), or should I give it a try? If the latter, what should the
commandline UI look like?

[1] I had a hard time getting httpd 2.4.4 to build with a debug
configuration. Apparently there is/was a bug in the libhttpd.dsp file
(should be fixed in 2.4.5). See
