Macros get expanded in comments..

["Mike A. Harris" <mharris meteng on ca>]

I have a spec file which I have a construct like:

%define this	that
#%define this    somethingelse

After a bit of hair pulling I found that the commented out macro
definition is acting as if not commented out after all.  Is this
a bug or a feature?  If the latter, how can I get the desired
operation?

In english, what I'm _really_ wanting to do is:

if( build_os <= Red Hat 6.2 )
	%define this	that
else
	%define this	somethingelse
fi


I have no idea how to state that in the spec file though, so I
figured I'd just manually comment out the %define for each build.

Any help would be greatly appreciated.

TIA
