This sounds very interesting. I have no experience with MinGW/MSYS, but
will most definitely start looking into it asap and see how hard it
would be to get the new build compatible with it.

So I did more test......
- I wanted to compare with MKS and the first thing I hit on was a bug
in MKS's 9.4 version
of cpio ("CFS# 32408--- cpio can not handle files which are
ReadOnly"). And it's expensive
and installation and license handling is PITA if you use several
virtual machiines..
- Still couldn't find the reason why the build hangs with Cygwin 1.7.10
Finally I decided to try something new - MinGW/MSYS.
And indeed - it worked, it's nearly as fast as MKS, it can use the
default make which comes
with the MinGW/Installation. Read the glory details at:
http://mail.openjdk.java.net/pipermail/build-dev/2012-March/005729.html
Please feel free to test, review and (hopfully) submit it.
The changes are intentionally against the old, "traditional" build system to fix
the mentioned Cygwin problems and simplify the Windows build just now.
As next steps I see the following points:
- integrate MinGW/MSYS with the new build system
- completely remove nmake from the HotSpot build and use prallel GNU make
like on Linux (I know this works and that it's faster - just have to
build a OpenJDK patch)
Any comments?
