# 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.
