Is _environ present in 7.0-RELEASE ?

[Ashish Shukla]

Hi all,

I'm running FreeBSD 7.0-RELEASE-p3 (amd64). I'm trying to install kde4 from scratch. I'm getting an error with building libxine-1.1.14. And as kde4 ports depends on libxine, 
I'm not able to build kde4. Following is an excerpt from the build output, I've received:

I've uploaded the config.log[1] present in ${PORTSDIR}/multimedia/libxine/work/xine-lib-1.1.14 . Since no one else has received any such error, I've not filed any PRs. 
Following is the test program I wrote to reproduce the error.

abbe [~] monte-cristo% cat test.c

#ifndef NULL
#define NULL (char**)0

}

---->8---->8----

The '__environ' symbol is also not defined. Can anyone hint me, what is misconfigured on my box ?
