-# of each subdirectory, eg: newlib, libio, etc.) until the right way to do
-# this (ha ha) is decided upon.

-# It is advisable to support a few --enable/--disable options to let the
-# user select which libraries s/he really wants.

-#else

-#
-# `with_multilib_top' exists to handle the case of configuring in the source
-# tree: ${srcdir} is not constant.

-#
-#if [ -n "${with_multilib_top}" ]; then

-# libraries as desired.
-#
-# FIXME: It would be better if we could use the --print-multi-lib switch to
-# gcc to get the list of directories to build, but at this point the compiler
