In spite of the trouble indicated above, I would like to experiment with
gcc 4.0, not necessarily only for building LFS though. I managed to
configure and compile gcc-4.0.0-20050410, with

   ../gcc-4.0.0-20050410/configure --enable-clocale=gnu --enable-shared \
   --enable-threads=posix --enable-__cxa_atexit --enable-languages=c,c++,java \
   --prefix=/usr/local/gcc-4.0.0-20050410

and

   make bootstrap MAKE="make -j 2" -j 2

but before comitting with a "make install", I am concerned about the
integrity of my system. Do I run a risk of destroying/polluting my
/usr/include or something else, or will *everything* be placed under
the prefixed-specified directory? Is there any standard way of doing
such things, some sort of "sandbox" technique that I may not be aware
of? Any advice greatly appreciated...

J.O.
