That is just an ugly hack and I wouldn't publicy advertize it :-)

BTW, if you can endure the slowness, you can also manually call the 
'msw-app.sh' script like this:

msw/msw-app.sh -s -n <version_suffix>

I think the best solution would be to actually support running Pd 
directly from the source tree (like we can already do on Linux and 
macOS). Unfortunately, this is not completely trivial. I just opened a 
ticket for this: https://github.com/pure-data/pure-data/issues/1957
