Usually these projects infrastructure can be stretched into
application specific domains with low enough cost and high enough
quality/performance. Nowadays, when free or open (or whatever they
call it now) projects supply such a large arsenal of optimizations, it
would probably make sense to write a compiler from scratch only if
your architecture doesn't involve something like instruction set,
registers, pipeline, and units.
