See the BUILD README. For sure you need the cygwin 'make', awk, ksh, and
more, the list should be in the openjdk build readme.
I myself just download all of cygwin, which takes a long time but
then I never have to worry about not having something

You should not need to build GNU make, however there is an issue with 3.80
on Windows where it doesn't work, due to it not accepting C:/ style paths.
See http://weblogs.java.net/blog/kellyohair/archive/2007/01/jdk_builds_on_w.html
Download a patched cygwin make binary from
http://www.cmake.org/files/cygwin/make.exe

And this is important: Start your 'make' from a cygwin shell window, NOT a
Windows command window.

That is how the binary plugs are delivered right now, a jdk7 image.
We are working on sparse binary plugs.

If you can create a .lib file from a .dll, that should work, I didn't spend
much time looking into this idea, wasn't sure how reliable it was.

Look at the BUILD Readme first. Then get 'make sanity' to pass.
Unfortunately without a t2k.lib, you won't get past the sanity check.

I'm wondering if you have read the right README. What README are you
refering too?
