We identified cygwin make's inability to handle driveletter paths as one of the big problems with the old build system when starting the build-infra work for jdk8. So we designed the new build system to not use any mixed paths to avoid this problem.
Yes, you are right for the building of the jdk but that's only a part of the whole job. When talking about tests -- jtreg in particular --, you need to go back to the path handled by Java on windows and in that case, cygwin path does not work at all, only windows path with letter and '/' are working... So mixed path is a good compromise on windows for building, testing and delivering the full product....

The problem with driveletter paths is also stated in the current README-builds.html and a number of workarounds are mentioned.
True, but all specific turn arounds for windows and cygwin and dependent third party software builds are disseminated all along the README-builds.html, which are making the build not so obvious. Even if one dislikes Windows, it is a so important platform for the Java ecosystem that it would make sense, from my point of view, to have a specific, Windows focused README...
I agree that documentation can always be improved however, and would encourage suggesting improvements to the current documentation rather than duplicating and making it redundant.
Ok..got the point

I went through the exercise of building openjdk 7-8 on Windows and concur it isn't trivial. But google helps and I found very the helpful Volker's blogpost very quickly. This problem should not be solved by adding extra pointer to workarounds. The build system on Windows should work with the latest Cygwin's make. I think that the openjdk community is big enough to influence and push through all necessary fixes into make.

Hi Dalibor

Everybody at Oracle and may be elsewhere knows how difficult is the task of building OpenJDK on WXP/W7. There was even in a previous OpenJDK contest a proposal for making this windows build smoother... Thus, the blog of Volker SIMONIS is really of a great help to avoid loosing time, energy and aspirine for building OpenJDK on Windows. I was specially redevable to Volker on the chapter about the specific version of Make 3.82 which in the standard cygwin delivery does not understand the Windows Letter based path. Without his guide on compiling and running the latest Make out of cygwin, NO ONE, and I repeat, NO ONE can make the OpenJDK because it fails without a clear and understandable errors. Moreover, when asking the build list about those errors, no one answers because no one can imagine that the Cygwin make cannot manage Windows letter based path.

So, yes, adding the blog of Wolker SIMONIS or may be a reformatted text*is a major help for building OpenJDK on windows*.

Please, reconsider your position on adding this blog post as a README file.

Hi

I submit this patch for review for this Bug ID: 9007227: - make/sanity-rules.gmk:61: *** multiple target patterns. Stop

The webrev.ksh is broken on WXP/Cygwin. So I am providing here the hg outgoing report as well as the new file README-Windows-Cygwin-VS2010
I don't think that it's necessary to include blog posts in the source code archives. ;)

cheers,
