Building and running fixincludes for the avr target is not necessary with the current canonical toolset of binutils, gcc and avr-libc: <http://savannah.nongnu.org/projects/avr-libc/>
Building fixincludes currently fails for host=mingw32 host, which being corrected with bug #17832. But building fixincludes for the avr target is unnecessary to begin with. A potential patch would follow the form found here: <http://gcc.gnu.org/ml/gcc-patches/2004-09/msg00934.html> -- Summary: Disable building of fixincludes for avr target. Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ericw at evcohs dot com CC: gcc-bugs at gcc dot gnu dot org GCC target triplet: avr-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18151
