There are two free compiler setups for Windows that I know of, both  
based on gcc.  http://MinGW.org and http://cygwin.org.  MinGW aims to  
me more Windows-like, and Cygwin aims to be UNIX on top of Windows.   
Cygwin is better supported and more complete, but its downside is that  
you need the cygwin.dll to run programs, and they behave somewhat  
UNIX-like.

I have started trying to port parts of Pd to MinGW.  It would be great  
if ultimately all of Pd would compile in MinGW so that Windows devs  
would have to buy (or ahem, "buy") a compiler.
