* It is impossible to get full supporting from ‘configure’
Getting runtime informations – ex bytes of ‘long’ type, checking whether symbol ‘xxx’ is in the library or not. – is impossible.
-> Some releases complain this and doesn’t proceed anymore.
* Some releases still refer /lib, /usr/lib, /usr/include etc.
* Using ‘make check’ in naive way is impossible.
* Anything else???
