OpenJDK 7 build fails on Snow Leopard

[Venkateshwaralu Srikarunyan]

Hi,

I am newbie and was trying to get started with the build for the OpenJDK 7.
I was following the wiki by Stephen
Bannasch<http://confluence.concord.org/display/%7Estepheneb>at

http://confluence.concord.org/display/CCTR/Build+OpenJDK+Java+1.7.0+on+Mac+OS+X+10.5

But ended up facing the following build error

/ucontext.h:42:2: error: #error ucontext routines are deprecated, and
require _XOPEN_SOURCE to be defined

Request for guidance from someone to help me get this build up and running.
Thanks.

My Environment looks like this

vsrikarunyan@~$ uname -s -r
Darwin 10.0.0

vsrikarunyan@~$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5646)
