Re: Merge current set of OpenACC changes from gomp-4_0-branch

[Gerald Pfeifer]

Once I work around the previous failure, I quickly get another one on
FreeBSD 8.4/amd64:

/scratch/tmp/gerald/gcc-HEAD/libgomp/target.c:67:12: error: 
\xe2\x80\x98num_devices\xe2\x80\x99 defined but not used 
[-Werror=unused-variable]
 static int num_devices;
            ^

This one did not require autoconf, so I went ahead and fixed it myself. 
;-)  Committed after successful bootstrap on x86_64-unknown-freebsd8.4 
(after hacking around the other failure).
