#   Script to build GCC 2.95.2 on HP-UX 10.20 using bundled C compiler
#	Assumes you have the following files available:
#       binutils-2.11.2.tar.gz
#       bison-1.28.tar.gz
#       flex-2.5.4a.tar.gz
#       gcc-3.2.tar.gz
#       gettext-0.10.35.tar.gz
#       make-3.79.1.tar.gz
#       sed-3.02.tar.gz
# Note: there are just enough inconsistencies in the way things have to
# be configured to make it difficult to generalize fully.  It is assumed
# that you have gunzip (or bunzip2) available if you have compressed
# files.  It is assumed that tar is available.
# Note that on HP-UX 11.11, some later versions of some of these
# utilities (bison, gettext) did not compile with the bundled C compiler
# when the script was run, but that manually rebuilding seemed to fix
# things -- no, I've no idea what the trouble was.

# All the GNU software will be placed under the $PREFIXDIR directory

# Utilities package.
