Re: [Ohrrpgce] New build system (Was: SVN: teeemcee/3714 I rewroteMakefile, for fast builds!)

[David Gowers (kampu)]

All outstanding issues have been addressed, except the "'clean'
target" one mentioned by Seth. I haven't been able to commit since my
login no longer seems to work, so I'll just attach these, for now.
(I have emailed James about the login, but thought that might take
some time to work out.)
