# Warning! There is no real "make install" support.
# The include files are named after the djb, i.e. pretty generic. They
# will probably conflict with other headers. That's why I install them
# in /opt/diet, where they are in the default search path for my diet libc
# work but don't conflict with anything there. YMMV.
