I checked the dates of all the configure.ac & configure. Here they are: ./fixincludes/configure.ac Jul 16 2005 ./gcc/configure.ac Feb 14 2006 ./intl/configure.ac Sep 22 2004 ./libcpp/configure.ac Oct 8 2005 ./libiberty/configure.ac July 21 2005 ./libmudflap/configure.ac Oct 4 2005 ./libssp/configure.ac Feb 27 2006 ./configure Sep 13 09:35 What should I do based on that ? Is there a way/flag to prevent the regeneration of configure ?

It's to do with timestamps. If the file configure.ac has been changed, gcc tries to regenerate the file configure. Have a look at the timestamps on configure.ac and configure. Andrew.
