Comment:
OK put a new spkg up. I have gone through the whole TODO list so the
changes have been a bit invasive. I made a new Makefile that uses
CXXFLAGS, LDFLAGS and CPPFLAGS - it could possibly use a little bit more
love before sending upstream. Scrap that it would need a fair rewrite to
get rid of a lot of stuff. Patch is now used throughout. Removal of the
old gfan install is now done after the build and done correctly - which it
wasn't before because of a misplaced double-quote.
I think that sums it up. Over to you Marshall to see if you like the whole
thing.
