Well, without a concrete example, I'm not sure we have much to go on.  We obviously do keep portability in mind.  The modularization of the server into DIX and DDX is one main example.  As another, we do our best to not to break (and fix) support for gcc-2.95 as it is used for sparc/BSD.  That's certainly larger than your purported 2-year scope of interest.  I believe that anyone interested in building the ToT X11 codebase will have at-least a 12 year old toolchain and POSIX environment at their disposal.
