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....

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...

Ok..got the point
