I'm trying to cross-compile Linux, and it keeps thinking that Windows is
defined,
so I am assuming the answer is yes.

May we have an option to undefine a version? (Of course, the option I'd prefer -
to not have any defined - will die in a howl of catcalls and bleats, so I'll not
even seriously propose it.)

For the moment, I'll get around this by putting the Linux blocks first ...

How about -version with no arguments?  That would cause every previously 
(or implicitly) invoked -version option to be forgotten (kind of like 
how -I- causes some compilers to forget the #include search path).

So in this case, you would use '-version' before any '-version=foo' 
option.

Of course, you might not always want to forget all default -version 
options, so maybe it's better to have an 'un-define' option implemented 
first.

I think of this as two questions:


1. Should we be able to undefine a version?

Maybe. I'm afraid we might be creating more problems for ourselves (new 
subtle errors), but I can see possible uses for this feature. Would the 
possible new problems be worth the new abilities? I don't know, but I 
think it's good to discuss these issues.



2. How would undefining version work?


Perhaps we could undefine all versions at once:

Maybe at the commandline we could use "-version=void"

And within the code, we could use:
version = void;


Or we could undefine individual versions.

version = void Windows;

Would that create an error if Windows wasn't previously defined?

version(Windows) version = void Windows;

I'm just thinking in written form.
