I think that this is not a direction that is going to work - the discrepancy is not in the sources, right? It all works here: $ find . -name md-\* ./powerpc-apple-darwin9/libgcc/md-unwind-def.h ./powerpc-apple-darwin9/libgcc/md-unwind-support.h ./prev-powerpc-apple-darwin9/libgcc/md-unwind-def.h ./prev-powerpc-apple-darwin9/libgcc/md-unwind-support.h ./stage1-powerpc-apple-darwin9/libgcc/md-unwind-def.h ./stage1-powerpc-apple-darwin9/libgcc/md-unwind-support.h $ find . -name unwind-dw2.o ./powerpc-apple-darwin9/libgcc/unwind-dw2.o ./prev-powerpc-apple-darwin9/libgcc/unwind-dw2.o ./stage1-powerpc-apple-darwin9/libgcc/unwind-dw2.o So .. what is the output of which make make --version I don't suppose that there's any chance of me persuading you that the right way to find the problem is to back out of all the complexity until you have a working build and then find out which addition is causing the problem?
