[dev] [sxiv] doesn't want to be compiled

[Cág]

Hi,

I feel a bit stupid right now. The output is:

---
LINK sxiv
/usr/local/lib/libImlib2.so.6.0: warning: warning: strcpy() is almost always 
misused, please use strlcpy()
/usr/local/lib/libImlib2.so.6.0: warning: warning: sprintf() is often misused,

misused, please use strlcat()

*** Error 1 in /home/caoc/code/suckless/sxiv (Makefile:30 'sxiv': cc  
-L/usr/X11R6/lib -L/usr/local/lib -o sxiv  -lImlib2 -lX11 -lXft -lgif ...)
---

I modified config.mk and Makefile (they are attached), so OpenBSD's make
can start at least. Someone please take a glance with fresh eyes.


Thanks
