When did you last audit these 66,000 lines of intermediate code, which people are encouraged to run as root? If you _had_ audited it, how would you know you hadn't missed something cunningly concealed in a double expansion somewhere?

address@hidden:~/build/guile-2.0.11$ wc -l Makefile lib/Makefile libguile/Makefile configure
   2373 Makefile
   4052 lib/Makefile
