I'm trying to build lambdabot 4.0 with ghc-6.4.1 (gcc (GCC) 3.4.2 (mingw- special)) and Cabal-1.1.6.1 on WinXP SP2. I've got as far as Plugin.Pl.Transform.hs, and I get

Transform.hs uses {-# OPTIONS -fvia-C -O2 -optc-O3 #-}
The mangler probably isn't expecting the sort of output gcc -O3 generates on Windows. I don't think we do any testing at that level of gcc optimisation. I'd recommend just using -O2, or lower if necessary, instead. Thanks Ian
