Cygwin has setfacl and getfacl. IIRC cygwin does just enough windows acls to implement un*x permissions semantics, so keep in mind it might not give you everything. (BTW where is your setacl, I have windows xp and could not find it, and so could not contrast the output of both set*acl).
If you don't care for a "normal install" using cygwin setup, do the following:
Get the "cygwin" package (just 1 package) for example the latest one say with 'curl -O ftp://ftp.heanet.ie/pub/cygwin/release/cygwin/cygwin-1.5.24-2.tar.bz2' (-big-Oh not -zero)
extract it somewhere and just put the *facl and cygwin1.dll in a directory you can access from your code
try running getfacl from there; if it does not work get the ash package, proceed as before but run getfacl from ash.
IIRC directories have also a default acl...note that *I do not do acls* ;)
At least that gives something to try if you're stuck. Good luck.
