So, as you can see it is not a simple ifdef.  This could take some time 
to fix, or it might be quick. The initialization of compilers is a very 
tricky part of CMake, and changes often break things in hard to detect 
ways.  We have plenty of linux machines, just not plenty of time...   It 
is on the list of things todo.

One thing that might help you understand what is going on, is the new 
--trace option.  It will show you every statement and file cmake 
includes.
