Hello,
running "make DESTDIR=~/gnu64 install-data" on the master-x86_64 branch produces a broken "machine" symlink inside ~/gnu64/include that points to a non-existent x86_64 directory. That breaks building of mig. This is due to line "ln -s '$(systype)' '$(DESTDIR)$(include_machdir)'/machine" in Makefrag.am. Maybe we could add an x86_64 -> i386 symlink, or perhaps better duplicate the i386 directory with name x86_64 and work on that. Andrea
