success in building emacs-19.34 on redhat 7.3

[Lee Campbell]

I wanted to build emacs-19.34 on my redhat 7.3 system so I can have my
choice between smart data-type-aware emacs-21 and old emacs-19.34 that
loads fast and treats everything as raw ASCII.

I started with a tarball called emacs-19.34b.tar.gz which can be found
at ftp://prep.ai.mit.edu/pub/gnu/emacs/, and the default gcc-2.96-110.
I used the patches described in
   http://ww.geocrawler.com/mail/msg.php3?msg_id=4539022&list=337
which allowed it to compile, but it would still core-dump when it
ran.  That was fixed by adding "-z nocombreloc" to the LDFLAGS in the
makefile, as described in:
   http://sources.redhat.com/ml/binutils/2001-10/msg00574.html
Now it works fine, and loads amazingly faster than emacs21!

P.S.: To be specific, my ./configure line is:

  ./configure i386-redhat7-linux-gnu --with-x11 \
          --prefix=/usr/built/emacs-19.34

(the --prefix puts the binaries near the src tree.  I made a softlink
called /usr/local/bin/emacs19 to run it.)

Then I edited the Makefile (probably should have edited Makefile.in)
so that this original section:

  ${SUBDIR}: ${SUBDIR_MAKEFILES} FRC
        cd $@; $(MAKE) all $(MFLAGS) \
          CC='${CC}' CFLAGS='${CFLAGS}' CPPFLAGS='${CPPFLAGS}' \
          LDFLAGS='${LDFLAGS}' MAKE='${MAKE}'

now ends like this:

          LDFLAGS='${LDFLAGS} -z nocombreloc' MAKE='${MAKE}'


Here are the patches that worked for me (I cut'n'pasted manually)

And that's all there is to it!
