Reading the mailing list archive it seems that those errors happen and most of the time it's difficult to know where they come from. I found that it is possible to ignore those Overlaps with -O i. Now i get different errors which at least make sense to me.

Even then the resulting resource usage is 118% of available flash memory. The dict_appl.inc file used is empty, so i'm not sure what to modify there, because as i understand it this file is meant to include extra words. Does that mean that it is practically impossible to use amforth on an atmega8? If not, are there some example projects using it (i haven't found any)?
