control-center won't compile on Solaris 2.7

[Aaron Ginn <aaron ginn motorola com>]

I'm having difficulty getting control-center to compile on Solaris 2.7. 
Make errors out with this message:

ld: warning: file ../../control-center/.libs/libcapplet.so: attempted
multiple inclusion of file
Undefined                       first referenced

The function getline appears to be undefined.  If I look in the file
lister.c, the first line is

#define _GNU_SOURCE             /* For getline() */

It doesn't appear that _GNU_SOURCE is being defined as anything.  Is
this correct? Also, my header files that have been included are as
follows:

#include "da.h"
#include <sys/types.h>
#include <utime.h>
#include <errno.h>

In which header file is getline() defined, and why can't I see it?

Thanks,
Aaron Ginn
