Hello All,
[[this a bug I am encountering while merging the trunk into GCC MELT, but I can reproduce it under trunk only, so I don"t speak of MELT anymore; very probably I have bad versions of required utilities, but I cannot find which]] I have a pristine GCC trunk rev 167234 under /usr/src/Lang/gcc-trunk-bstarynk I want to regenerate its topmost ./configure so I run the following commands under the source tree /usr/src/Lang/gcc-trunk-bstarynk ## clean up every auto* dirt % rm -rf autom4te.cache */autom4te.cache ### version of autogen, and then I run it % autogen --version autogen (GNU AutoGen) - The Automated Program Generator - Ver. 5.10 % autogen Makefile.def ## version of autoconf, and then I run it % autoconf --version autoconf (GNU Autoconf) 2.64 Copyright (C) 2009 Free Software Foundation, Inc.

AFAIK, trunk still requires autoconf 2.64? Or what is the correct procedure to regenerate a correct ./configure ?
