# Configure fragment invoked in the common section for subdirs
# wanting multilib support.
#
# The common section was chosen because xiberty clobbers $srcdir in the
# common section of its configure.in.
#
# The intent is to keep as much of this in one place as possible (and out
# of each subdirectory, eg: newlib, libio, etc.) until the right way to do
# this (ha ha) is decided upon.
#
# This is where a target selects what multilib directories to build.
# It is advisable to support a few --enable/--disable options to let the
# user select which libraries s/he really wants.
#
# FIXME: Multilib is currently disabled by default for everything other than
# newlib.  It is up to each target to turn on multilib support for the other
# 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
# has not been built.

# Only do this if --enable-multilib.
# And only if at the top level, not a multilib subdirectory.
