# 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

# 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
