You guessed it right! To start, we will port the "dylp" subset (for
relaxed LP) of bonsai to Osi.

Thanks for the encouragement.

I assume the code is portable to solaris, as the unit test runs okay.
However, the makefiles requires some minor tweakings: 

1) ./Makefile.SunOS is not included in ./Makefile.coin
2) in {Osi,...}/Makefile, "wc" is assumed to produced statistics at
   7th column. It is true in linux but, in solaris, "wc" produces at
   8th column - failing to make the dependency file targets.

Anyway, it is a very minor problem. Who's reponsible for maintaining
makefiles?

We are developing on solaris, so if anything breaks in solaris we will
for sure bug you for that.
