Yep, I've just had a look and possibily fixed the Intel and HPUX cases.

The AIX one fails because the visibility test passes, because 
check_cxx_compiler_flag does not have a FAIL_REGEX for its warning:

http://www.cdash.org/CDash/testDetails.php?test=109778717&build=1458523

http://www.cdash.org/CDash/testDetails.php?test=110283056&build=1458523

I've also pushed a possible fix for that to check_cxx_compiler_flag on the 
branch.

The CentOS machine seems to have problems unrelated to this test:

http://www.cdash.org/CDash/testDetails.php?test=109887854&build=1457339

http://www.cdash.org/CDash/viewTest.php?buildid=1457339

All have ' undefined reference to `_Unwind_Resume'' in their output.

That only leaves Watcom as you say, and I've just tried to simplify the 
tests for that compiler. If the timeouts persist, I can start just disabling 
some tests for that compiler.

Hopefully that will be resolved in the next few days then :)

Thanks,

Steve.
