  I forgot to tell that the glibc-2.3.5 made with the stripped GCC
and the glibc-2.3.5 made with the complete GCC were different in
their library sizes, for instance the 'libc-2.3.5.so' was 1329938
bytes when produced with the stripped GCC but 1293873 bytes when
produced with the complete GCC. The SuSE 10.0/ppc one was 1510896
bytes for their glibc-2.3.5-40 (the 32-bit library). Whether
gcc-3.4.4 produces smaller code than gcc-4.0.2 (used in SuSE) or
then there are other big changes in their own glibc-2.3.5...

  Comparing those sizes is almost everything one could do simply,
but tools like 'nm' and 'objdump' could allow one to investigate
the differences more deeply...
