# configure.host

# This shell script handles all host based configuration for newlib.
# It sets various shell variables based on the the host and the
# configuration options.  You can modify this shell script without
# needing to rerun autoconf.

# This shell script should be invoked as
#   . configure.host
# If it encounters an error, it will exit with a message.

# FIXME: This script is too complicated.  It does things in too many
# different ways.  This was taken from the old Cygnus configure script
# with only minor changes.  It should be cleaned up.

# FIXME: The general approach of picking and choosing which
# directories to configure, other than machine_dir and sys_dir, is
# potentially confusing.

# It uses the following shell variables:
#   host		The configuration host
#   host_cpu		The configuration host CPU
#   newlib_mb		--enable-newlib-mb ("yes", "no")
#   target_optspace	--enable-target-optspace ("yes", "no", "")

# It sets the following shell variables:
#   newlib_cflags	Special CFLAGS to use when building
#   machine_dir		Subdirectory of libc/machine to configure
#   sys_dir		Subdirectory of libc/sys to configure
#   have_sys_mach_dir	Is there a machine subdirectory in sys subdirectory
#   posix_dir		"posix" to build libc/posix, "" otherwise
#   signal_dir		"signal" to build libc/signal, "" otherwise
#   stdio64_dir		"stdio64" to build libc/stdio64, "" otherwise
#   syscall_dir		"syscalls" to build libc/syscalls, "" otherwise
#   unix_dir		"unix" to build libc/unix, "" otherwise
#   use_libtool         flag: use libtool to build newlib?
#   aext                library extension - needed for libtool support
#   oext                object file extension - needed for libtool support
#   crt1                name of crt1 object if one is provided
#   crt1_dir            directory where crt1 object is found
