# Author: Mike Gruber

#
# This file automates the build process for the Rev. 2.1  m68hc1x port of 
# the GNU C compiler.  The script is invoked from the directory which 
# contains all of the files needed to build the port.
#
# The INSTALLDIR must be set to a directory in which the user has write
# permission.  The tools will be found in INSTALLDIR/bin after this script
# has run.
#
# !!!!!! NOTE !!!!!!
#
# I have switched from a Linux environment to FreeBSD.  In order to 
# successfully build this toolchain on BSD, you need to use gmake instead
# of make.  I also prefer the bash shell, so this script has the strange
# path to bash that you find on a BSD system.  Linux users will probably 
# want to execute this script with /bin/sh, and modify the MAKE variable 
# below back to just call 'make'.
