Not sure what the cause of the troubles are with go and gnat/ada : http://gcc.gnu.org/ml/gcc-testresults/2013-03/msg02413.html I know that I have a chicken and egg problem with gnat in that I need an ada compiler before I can proceed with a gcc bootstrap and I think I would need to dig deep into my history shelves to find that. What bothers me is "go". Are there some special requirements for "go" other than those required for GCC as a whole? I don't see anything documented for magic or some hidden incantation so I assume that a valid C compiler will do the job. However, it won't. I get simply horrible results for "go" within the exact same environment that builds the above result. hints? nudges or outright shoves are appreciated. Dennis
