I'm using gcc on Linux so I would say it's relevant.

To give you an example, building the regex lib for pentium4 and afterwards 
for athlon does not trigger a new build. The difference with the 
-sBUILD=debug is only that the latter adds an extra sub-dir 
runtime-link-dynamic.

OTOH, trying to do the same for the python library, I get following error :
