JDK7 build under windows

[Kelly O'Hair]

Since some of the tools used during the build (like ant, java, etc.)  
do not understand the cygwin style paths
like /cygdrive/c/, you need to use the so called 'mixed style' of  
drive letters and / characters, e.g. C:/
You can use the command 'cygpath -m -s -a' on a path to get the right  
style, e.g.
    export ALT_BOOTDIR=`cygpath -m -s -a "${ALT_BOOTDIR}"`

The -m gets you mixed style, the -s gets you a short path without  
spaces, and the -a gets you an absolute path.
But the path needs to exist for cygpath to work.
