The builds were always done on MSR machines, although Sigbjorn used to bundle them up into installers. These days the MSR machines make the installers too, with a script from Neil. > For the record I'm using the Windows version of GHC 6.8.2 downloaded > from here > > http://haskell.org/ghc/download_ghc_682.html I'm pretty sure that's got the libraries built with -O, although I haven't looked for the log of that actual build. We only use -O2 on the Linux builds as far as I can see, but I'm not sure there's a good reason for that. I also don't know why we don't just make our preferred settings the default in the build system; Simon?
