Thank you Ralf for quick answer. It helps a lot. Truth to tell I did not read all GNU guide line since it's quiet a huge reading. You guess right: I was indeed using AM_MAINTAINER_MODE in the original project and I had just copy/cut it when I did the test project... my mistake. Everything works just fine now with the info files built in the source tree if that is what GNU recommends. In fact I was expecting that ``distribution files'' explanation. Thank you again.
Best regards, Ben
