+=head1 DESCRIPTION
+
+Perl 5.7/8.x for DG/UX ix86 R4.20MU0x
+
+=head1 BUILD
+
+=head2 Non-threaded Case
+
+Just run ./Configure script from the top directory.
+Then give "make" to compile.
+
+=head2 Threaded Case
+
+If you are using as compiler GCC-2.95.x rev(DG/UX)
+an easy solution for configuring perl in your DG/UX
+machine is to run the command:
+
+./Configure -Dusethreads -Duse5005threads -des
+
+This will automatically accept all the defaults and
+in particular /usr/local/ as installation directory.
+Note that GCC-2.95.x rev(DG/UX) knows the switch
+-pthread whcih allows it to link correctly DG/UX's
+-lthread library.
+
+If you want to change the installtion directory or
+have a standard DG/UX with C compiler GCC-2.7.2.x
+then you have no choice than to do an interactive
+build by issuing the command:
+
+./Configure -Dusethreads -Duse5005threads
+
+In particular with GCC-2.7.2.x accept all the defaults
+and *watch* out for the message:
+
+====
+Any additional ld flags (NOT including libraries)? [ -pthread]
+====
+
+Instead of -pthread put here -lthread. CGCC-2.7.2.x
+that comes with the DG/UX OS does NOT know the -pthread
+switch. So your build will fail if you choose the defaults.
+After configuration is done correctly give "make" to compile.
+
+=head2 Testing
+
+Issuing a "make test" will run all the tests.
+If the test lib/ftmp-security gives you as a result
+something like
+
+=====
+lib/ftmp-security....File::Temp::_gettemp:
+Parent directory (/tmp/) is not safe (sticky bit not set
+when world writable?) at lib/ftmp-security.t line 100
+=====
+
+don't panic and just set the sticky bit in your /tmp
+directory by doing the following as root:
+
+cd /
+chmod +t /tmp (=set the sticky bit to /tmp).
+
+Then rerun the tests. This time all must be OK.
+
+=head2 Installing the built perl
+
+Run the command "make install"

-# Here are the things from some old DGUX hints files which are different
-# from what's in here now. I don't know the exact reasons that most of
-# these settings were in the hints files, presumably they can be chalked
-# up to old Configure inadequacies and changes in the OS headers and the
-# like. These settings might make a good place to start looking if you
-# have problems.
-#
-# This was specified the the 4.036 hints file. That hints file didn't
-# say what version of the OS it was developed using.
-#
-# cppstdin='/lib/cpp'
-#
-# The 4.036 and 5.001 hints files both contained these. The 5.001 hints
-# file said it was developed with version 2.01 of DGUX.
-#
-# gidtype='gid_t'
-# groupstype='gid_t'
-# uidtype='uid_t'
-# d_index='define'
-# cc='gcc'
-#
-# These were peculiar to the 5.001 hints file.
-#
-# ccflags='-D_POSIX_SOURCE -D_DGUX_SOURCE'
-#
-# # an ugly hack, since the Configure test for "gcc -P -" hangs.
-# # can't just use 'cppstdin', since our DG has a broken cppstdin :-(
-# cppstdin=`cd ..; pwd`/cppstdin
-# cpprun=`cd ..; pwd`/cppstdin
-#
-# One last note: The 5.001 hints file said "you don't want to use
-# /usr/ucb/cc" in the place at which it set cc to gcc. That in
-# particular baffles me, as I used to have 2.01 loaded and my memory
-# is telling me that even then /usr/ucb was a symlink to /usr/bin.

# The standard system compiler is gcc, but invoking it as cc changes its

# dynamic loading switches right (they vary depending on this). I'm
# picking gcc because there's no way to get at the optimization options
# and so on when you call it cc.
