-# Perl Configure hints file for Hewlett-Packard's HP-UX 9.x and 10.x
-# (Hopefully, 7.x through 11.x.)
-#
-# This file is based on hints/hpux_9.sh, Perl Configure hints file for
-# Hewlett Packard HP-UX 9.x
-#
-# Use Configure -Dcc=gcc to use gcc.
-#
-# From: Jeff Okamoto <okamoto@corp.hp.com>
-# and
-# hints/hpux_10.sh, Perl Configure hints file for Hewlett Packard HP-UX 10.x
-# From: Giles Lean <giles@nemeton.com.au>
-# and
-# Use #define CPU_* instead of comments for >= 10.x.
-# Support PA1.2 under 10.x.
-# Distinguish between PA2.0, PA2.1, etc.
-# Distinguish between MC68020, MC68030, MC68040
-# Don't assume every OS != 10 is < 10, (e.g., 11).
-# From: Chuck Phillips <cdp@fc.hp.com>
-# HP-UX 10 pthreads hints: Matthew T Harden <mthard@mthard1.monsanto.com>

-#--------------------------------------------------------------------
-# Use Configure -Dcc=gcc to use gcc.
-# Use Configure -Dprefix=/usr/local to install in /usr/local.
-#
-# You may have dynamic loading problems if the environment variable
-# LDOPTS='-a archive'. Under >= 10.x, you can instead LDOPTS='-a
-# archive_shared' to prefer archive libraries without requiring them.
-# Regardless of HPUX release, in the "libs" variable or the ext.libs
-# file, you can always give explicit path names to archive libraries
-# that may not exist on the target machine. E.g., /usr/lib/libndbm.a
-# instead of -lndbm. See also note below on ndbm.
-#
-# ALSO, bear in mind that gdbm and Berkely DB contain incompatible
-# replacements for ndbm (and dbm) routines. If you want concurrent
-# access to ndbm files, you need to make sure libndbm is linked in
-# *before* gdbm and Berkely DB. Lastly, remember to check the
-# "ext.libs" file which is *probably* messing up the order. Often,
-# you can replace ext.libs with an empty file to fix the problem.
-#
-# If you get a message about "too much defining", as may happen
-# in HPUX < 10, you might have to append a single entry to your
-# ccflags: '-Wp,-H256000'
-# NOTE: This is a single entry (-W takes the argument 'p,-H256000').
-#--------------------------------------------------------------------
-
-# Turn on the _HPUX_SOURCE flag to get many of the HP add-ons
-# regardless of compiler. For the HP ANSI C compiler, you may also
-# want to include +e to enable "long long" and "long double".
-#
-# HP compiler flags to include (if at all) *both* as part of ccflags
-# and cc itself so Configure finds (and builds) everything
-# consistently:
-# -Aa -D_HPUX_SOURCE +e
-#
-# Lastly, you may want to include the "-z" HP linker flag so that
-# reading from a NULL pointer causes a SEGV.
