This is into /home/mark/opt/gcc-svn-src

I then configured with ./configure --prefix=/home/mark/opt/gcc

I then did make:

I would be happy to try to build a slightly earlier and more stable version but
don't know how. (With mercurial I'd do 'hg update _an_earlier_tag' but don't
know the svn equivalent if there is one.)

I bet this is just a problem with you building in the src directory.  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)?

I'm v. sorry, I read the instructions carefully but still managed to miss the
point about doing the build out of tree since I don't need to do that for other
things. 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.

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.
