mcsim using MinGW on Windows XP

I am about to embark on compiling and setting up mcsim to use mingw on
Windows XP.  I did this a long time ago with a much earlier version of
mcsim, but I gather others have already done this with the current
version-- would you be willing to share what I need to do?
Thanks!
