Well there is a reason why it is part of the modifying GCC section. building GCC section is for building from releases. While modifying GCC section is for building from svn and snapshots.

I've now built it sucessfully. Thanks! PS I had to do 'make realclean' in the source directory before it would build. PPS Thanks also for mentioning flex: maybe it should be moved to the "Tools/packages necessary for building GCC" section (currently it is in the "Tools/packages necessary for modifying GCC" section) on page http://gcc.gnu.org/install/prerequisites.html since I only read the former since I just want to try to use the leading edge version, not modify it.

This is not always supported and not always 100% working. Can you try building in an object directory? Also do you have flex since that is required while building from subversion (but not from the release tarballs)?
