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.

I am trying to build openjdk7 b100 under Windows Server 2008 SP2.
I am using cygwin 1.7+
I am having trouble with openjdk/langtools/make
The Makefile there sets up some java support for Ant using the
ALT_BOOTDIR, which therefore must be a valid cygwin path, such as /
cygdrive/c/DEVELO~1/JDK/bootJDK/JDK16~1.0_1
However if set to a cygwin style path, the ant build.xml in openjdk/
langtools/make fails because it uses the available task to test the
correctness of the boot.java.home property ( set from the same
Makefile which had to have the cygwin path ). As you doubtless know
( http://ant.apache.org/manual/platform.html ) when ant is executed
by cygwin it still expects Windows path names. I could doubtless
hack the build.properties or Makefile to set the boot.java.home to a
windows path, but I am concerned that I am doing something else
wrong which I will have to fix again and again.
What format should ALT_BOOTDIR have when running cygwin? Windows or
cygwin? Is there some property file I can edit to satisfy all the
build?
Here is the output of an edited build.xml when I set ALT_BOOTDIR to
a cygwin path ( see below for the redefined macro, check...
