xine-lib from pkgsrc

[Jonathan Fosburgh]

After several months I finally have DragonFly working again (my pc at work was 
upgraded to an HP system with an unsupported NIC).  Since it has been so long 
I wiped out all of my packages and started over with pkgsrc.  In general 
things are working OK, and in fact I have a useable KDE desktop now.  
However, I am running into a few problems, the first one I wish to tackle is 
xine.  

I am running 1.3.7.  (DragonFly jef-nt.mdacc.tmc.edu 1.3.7-DEVELOPMENT 
DragonFly 1.3.7-DEVELOPMENT #4: Tue Oct 18 12:20:42 CDT 2005     
root at xxxxxxxxxxxxxxxxxxxx:/usr/obj/usr/src/sys/vmbsd  i386
)   My pkgsrc is (as far as I know) current, not tracking any branches so I 
should have all of the latest fixes.  The first problem with xine-lib is that 
configure breaks due to the lack of a -lpthread.  I can fix this by editing 
the configure script to check for -pthread instead. This works well enough to 
get through configure. 

xine-lib proceeds to build, but stops 
in /usr/pkgsrc/multimedia/xine-lib/work/xine-lib-1.0.3/src/input/libdvdnav 
with the following error:

I can make this section compile by adding the following to bswap.h (in the 
libdvdnav directory):


#elif defined(__DragonFly__)
#include <sys/endian.h>
#define B2N_16(x) x = be16toh(x)
#define B2N_32(x) x = be32toh(x)
#define B2N_64(x) x = be64toh(x)

This is added at line 62. It works to compile, but  I basically just copied it 
from the FreeBSD section above, so I don't know if it is right.  

Is there a better fix in place for the lpthread problem? It appears 
libthread_xu isn't quite ready yet.  Also, am I setting the above defines 
correctly? If that is right I would be happy to submit a patch to the 
appropriate people.
