AIX smoke failures

I'm looking at the smoker failures.  We're in pretty good shape except 
for HP-UX and AIX, and some transient failures in some other platforms.

This email covers AIX.

There is just one failure in the xlc version.  And it is not a blocker. 
  Just a warning that returns an extra line beyond what is expected when 
stdio is used

EXPECTED:
Filehandle STDOUT opened only for output at - line 3.
GOT:
Filehandle STDOUT opened only for output at - line 3.
Unable to flush stdout: Error 0

On the gcc version, there are some other failures regarding h2ph and 
h2xs.  Also not blockers.

However, when I run it using cc on Tux's machine, I get more errors. 
Just about all of the extras are because of failure with floating point 
Infinity, and it appears that these tests should just be skipped here. 
I guess one shouldn't use cc on this platform.
