CF		 1# configure.host
2
3# This shell script handles all host based configuration for newlib.
4# It sets various shell variables based on the the host and the
5# configuration options. You can modify this shell script without
6# needing to rerun autoconf.
7
8# This shell script should be invoked as
9# . configure.host
10# If it encounters an error, it will exit with a message.
11
12# FIXME: This script is too complicated. It does things in too many
13# different ways. This was taken from the old Cygnus configure script
14# with only minor changes. It should be cleaned up.
15
16# FIXME: The general approach of picking and choosing which
17# directories to configure, other than machine_dir and sys_dir, is
18# potentially confusing.
19
20# It uses the following shell variables:
21# host The configuration host
22# host_cpu The configuration host CPU
23# newlib_mb --enable-newlib-mb ("yes", "no")
24# target_optspace --enable-target-optspace ("yes", "no", "")
