> It is possible you have found bug in Lunar's plugin management. It would be very bad thing if lunar update would set default gcc plugin to 4.4 if gcc 4.2 is still in use. If you confirm this bug I will look at it more closely and provide some kind of fix to keep gcc and plugin version bound together. You can now have other problems with features which came with gcc4.4 like phenom, autodetect, new Intel sse... not present in older gcc. Make sure in Lunar menu you have set as default the right plugin. Gcc plugin and gcc version must equal to match features they provide.

as i fixed my system manually now, i can't test it anymore. However, the 
manpage even states you can use "sse+387". I never had any problems with 
387,sse and i'm using those settings since i started ago some years with 
lunar.

So let's hope nobody else comes into such trouble.
