--- Comment #12 from Kai Tietz <ktietz at gcc dot gnu.org> 2013-01-16 09:51:45 UTC --- Created attachment 29176 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29176 Patch for using recursive copy for directories. AFAIU we are talking about libada only here. I agree that it is too late for an libtool update for 4.8 gcc. As suggested the changeLog for libada/ * Makefile.in (LN_S_RECUSIVE): New. (adainclude, adalib): Use LN_S_RECURSIVE for copy. As soon as libtool got updated this patch can be removed.
