I understand. But somebody better fix the instructions on the web site, which
show not only that but -fno-implicit-templates, the subject of another recent
bug report.

If you want to save additional space during the bootstrap and in the final
installation as well, you can build the compiler binaries without debugging
information as in the following example. This will save roughly 40% of disk
space both for the bootstrap and the final installation. (Libraries will still
contain debugging information.)

          make CFLAGS='-O' LIBCFLAGS='-g -O2' \
            LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap

It does talk about "non-standard CFLAGS" a few paragraphs below this, but only
in referring to libiberty. It's unclear what is meant by "non-standard".

What is needed is an actual example of a recommended command line.
