OK, I finally found why I got this error message. When fastjar 0.94 is installed on my system, if I try to build gcc 5.3.0, I got this error. However, if I remove fastjar from my system, building gcc works fine. So, I guess that when fastjar is installed on my system, the building system of gcc automatically use this external program in order to manage jar files. Is there a way to configure the building system of gcc in order to avoid using this external fastjar version please?
