I did indeed fix the Intel and HPUX cases.

The FAIL_REGEX I added for AIX was successful. However, now that box reports 
some garbage:

  ld: 0706-014 The -b
  Tests/CMake-
build/Tests/Module/GenerateExportHeader/libsharedtest/fail1/libshared
  option is not recognized.

Someone with access to the box would have to find out what's going wrong. It 
might have been caused by a space in the path, which I've just added a fix 
for. 

It might be worth running some tests twice: Once from a path with a space in 
it, and once without. Or run all tests from a path with a space in it to 
prevent these kinds of bugs.

I would prefer to turn off the tests for it anyway, but I don't know what 
platform test to make. What is the equivalent to 

if (WIN32)
  return()
endif()

for AIX?

Do I have to do anything about this?

This one is still timing out. I've disable the test for it with 
(CMAKE_COMPILER_FLAG MATCHES "Watcom").

Thanks,

Steve.
