Generic install:
./configure
make
make install

Right now, the only options for the configure script is 
--prefix=/path  to specify the directory prefix for installing xinetd.
--with-libwrap=[path] to specify that you would like libwrap compiled in.

Other options, such as what signals do what, where the default paths
point for things like the config file and the debug dump file, default
limitations, etc can all be configured in xinetd/config.h

Please take a look at the config file before using it.  A default config
file is in xinetd/sample.conf.  I can almost guarantee you'll have
problems if you use the default config file.
