Are you talking about #ifdef and #ifndef blocks littering the code?  
So you want the code with the correct constructs for your platform 
included but without the clauses that apply to other platforms?  If 
so, your editor may have a feature to "collapse" the code based on 
the values of the #defines you specify.  The one I use does this 
using a feature called "Selective Display."  (If you don't define 
DEBUG, for example, all #ifdef DEBUG constructs disappear.)  It also 
allows you to just copy the visible lines (those selectively 
displayed), which I think is what you want.  Just copy and paste into 
a new file.
