And you are right GraphicsMagick uses OpenMP, which means the comparison between Clang and the rest of the compilers are totally meaningless. 7-Zip builds just fine for me with Clang, I have no idea why they couldn't get it to build.

phoronix is an ad machine and solely strives to make the graphs more 
interesting....  I've added Michael on cc and who has always corrected 
blatant errata for me in the past.

With regard to OpenMP -  Did it say if the -omp flags were used?  If not 
then I don't think gcc automatically turns it on.
