>Description:
The ia64 emulators "xski" & "gski" from pkgsrc/emulators/ski crash on amd64 but not i386.

It is apparently caused by an uncast 0 as a NULL arg to execlp().  Casting the terminanting argument from "0" to "(char *)0" prevents the crash.  My patches below also include the same fix for the freebsd version.

I'm not sure if using NULL would be more portable, but the arg to execlp() looks like it is expecting a char*.

Feel free to modify my patch to something more appropriate that still works...

>How-To-Repeat:
On amd64 build ia64 kernel and "skiload" boot loader

cd .../pkgsrc/emulators/ski && bmake install

cd to directory where "skiload" and ia64 kernel exist

run "xski skiload"

type "run" in command window

xski will crash


make sure xterm opens with "xski console" appears with "OK" boot prompt, and "Running" window with increasing "icnt: ...." counter appears

>Fix:
Build with included patches.

Can tell problem is fixed if running xski and
xterm opens with "xski console" appearing with "OK" boot prompt, and "Running" window with increasing "icnt: ...." counter appears
