Just to clarify what my use case is; for our project (Open MPI):

- we know that there are some uncompilable header files on some  
platforms (e.g., RHEL4U3 with a specific vendor's 32 bit compiler)
- we don't want to warn the user about it, because:
    - it's a known problem that will not be fixed
    - the problematic header file does not "belong" to us; it's not  
our prevue to fix it
    - our code can handle not using the problematic header (and the  
features that it provides)
- when compiling on this platform with this compiler, we just want  
HAVE_INFINIBAND_DRIVER_H not defined, so that our C code can react  
accordingly

In short: all we want is a simple "no" result from the test.

Does that make sense?
