System: Linux blade.devel.redhat.com 2.4.5-10smp #1 SMP Wed Jun 27 14:24:51 EDT 2001 i686 unknown
Architecture: i686

>Description:
	The util_dup.c source file defines a function named g_strdup()
	which appears to be unused.  This symbol conflicts with a
	similarly-named function in the glib library, which is used by
	the GTK+ toolkit and various other programs.  There could be other
	conflicts in naming, because both make use of "g_" as a prefix
	for function names, but this is the case that I've been told
	about.  The original posting is at:
	http://mail.gnome.org/archives/gtk-list/2001-July/msg00122.html
>How-To-Repeat:
	Sample C program which will link successfully with libgssapi_krb5
	or glib:
		#include <glib.h>
		#include <krb5.h>

		int
		main(int argc, char **argv)
		{
        		int i = (g_strdup("Test string") != NULL);
        		return !i;
		}
	Can be built by running:
	gcc -o example `glib-config --cflags` -I/usr/kerberos/include example.c `glib-config --libs`
	or:
	gcc -o example `glib-config --cflags` -I/usr/kerberos/include example.c -L/usr/kerberos/lib -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err
>Fix:
	Is it possible to rename the functions using a different prefix?

 Thanks for pointing this out.  I know that the g_* functions in the
 gssapi library are potentially problematic.  This also goes into the
 general issue of namespace invasion, which overall we're rather bad
 at.  We will, in time, reduce the number of these namespace conflicts,
 but it is not a terribly high priority at the moment.
