Strange.  No such problems here.  Maybe this is an i386 or an
installation issue?t

Only flex generates invalid C++ code, so I added this to the INSTALL:


    Debian GNU/Linux unstable gcc-3.0
    ---------------------------------

       Flex (2.5.4a-11) in unstable does not produce g++-3.0 compliant C++
    code.  To compile LilyPond with gcc-3.0 you may do:
                 CC=gcc-3.0 CXX=g++-3.0 ./configure
                 make conf=gcc-3.0 -C lily out-gcc-3.0/lexer.cc
                 patch -p1 < lexer-gcc-3.0.patch
                 make conf=gcc-3.0 -C lily


with lexer-gcc-3.0.patch:
