Since today, I am ready with a OSS replacement of an inportant part of the tool 
chain.

In order to compile Illumos, you not only need the Sun Studio compiler and Java 
but also /usr/lib/cpp which is a K&R C preprocessor that is neither part of the 
onnv consolidation nor part of the Sun Studio consolidation. It was rather 
unrelated closed source software distrubuted together with SXCE and Indiana 
under unknown license rules.

/usr/lib/cpp is more important than I thought before checking it's relevance.
It is used by rpcgen(1), dtrace(1), aw(1) and as(1) and it is called 1421 times 
when compiling Illumos. Today a full "nightly" succeeded with the OSS 
replacement I wrote.

Now we really only need to take care of the compiler and Java.
