Hi Gus,

Thanks for the bug report.  Did you successfully build the original  
mpich2-1.0.8 (non-patch) release with these same PGI compilers?  The  
changes from 1.0.8 to 1.0.8p1 are pretty small [1] and I don't see how  
they would have altered your ability to build MPICH2 with the PGI  
compilers.

Things might be better in the latest 1.1b1 release, but I doubt it.   
I'm not sure exactly what form of inline assembly the PGI compilers  
use, but we can make an effort to support it in the 1.1.0 stable  
release if this is important to you.  The inline assembly in the PGI  
manual looks like gcc-style, so we might just have a bad configure  
test.  Would you mind sending us the output from configure as well as  
the config.log?  You can send it to me directly to avoid spamming the  
list with log files.  That should help me figure out what's going on  
with the configure test since I don't have a copy of the PGI compilers  
installed anywhere handy.

In the mean time you could install one of the other channels such as  
ch3:sock for the PGI-compiled version.  The intranode performance  
won't be as good but it should work just fine.
