It is working without the space. But that is not the behaviour I would 
expect.

That's what I expect, what I don't expect is that the '#' is lost in the 
end.

The macro-expander should ignore it, not remove it. Maybe it's not the 
macro-expander that is removing it, but in the end configure is ran where 
I would have expected it was still commented out.

Because I wouldn't expect a space before a macro would cause the 
macro-expander to actually NOT expand the macro and leave the space.
(Just as a space before a command in a shell-script would still work)

And I would expect that when a '#' is before a macro, the macro-expander 
leaves the '#' in place.


Both would be regarded a bug in my book ;) Would you accept a bug-report 
in Bugzilla for any of these ?
