--- Comment #13 from Ralf Corsepius <ralf_corsepius at rtems dot org> 2012-03-13 14:16:10 UTC --- (In reply to comment #11) > (In reply to comment #7) > BTW: The -mmcu=at90s2313 from above is fallout from -print-multi-lib. Well, IMO, --print-multi-lib is the only legitmate configuration. FYI: I could provide an alternative configuration for RTEMS, but avr-gcc-4.7.0 currently does not build at all due to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52925 rsp. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52575.
