>Description:
Building net/trafshow fails as follows on systems using GCC4:

gcc -pipe -O2 -I/usr/include -Wall -I. -DHAVE_CONFIG_H  -D_REENTRANT -c screen.c
screen.c:154: error: static declaration of 'curs_dock_x' follows non-static declaration
screen.c:44: error: previous declaration of 'curs_dock_x' was here
screen.c:154: error: static declaration of 'curs_dock_y' follows non-static declaration
screen.c:44: error: previous declaration of 'curs_dock_y' was here
*** Error code 1

Stop.
bmake: stopped in /Volumes/NetBSD/pkgsrc/net/trafshow/work/trafshow-5.2.1
*** Error code 1

Stop.


After applying the first patch, below, the build again fails on MacOS
X 10.4.6 as follows:

>How-To-Repeat:
The first problem will appear if one attempts to build net/trafshow
on any system using GCC4.

The second problem may be specific to MacOS X 10.4.? and will appear
when one attempts to build net/trafshow on MacOS X 10.4.x.
>Fix:
The first problem is just bad or sloppy programming.  The following
patch fixes it:

--- work/trafshow-5.2.1/screen.c.orig   2006-06-02 12:48:14.000000000 -0500
+++ work/trafshow-5.2.1/screen.c        2006-06-02 12:48:37.000000000 -0500

The second problem appears to affect MacOS X 10.4.x systems only,
due to some variations in macro definitions.  This may be worked
around by the following patch:

--- work/trafshow-5.2.1/domain_resolver.c.orig  2006-06-02 12:56:12.000000000 -0500

Following application of both these patches, net/trafshow builds,
installs and runs just fine on MacOS X 10.4.6
