I'm afraid you could have saved yourself most of the effort.  There's 
already a patch out there doing that.  See

http://sourceforge.net/tracker/?func=detail&aid=1757226&group_id=2055&atid=302055

Had you investigated that earlier, you might have stumbled over the
patches tracker the above link points into...

docs/gnuplot.doc.  And you'll have to either 'make install' or set the 
GNUHELP environment variable for it to locate the freshly built version. 
  While working in the source tree in a Unix-like environment, it helps 
to have a little script in gnuplot/src that goes like this:

#! /bin/sh
#GNUTERM=x11
GNUHELP=../docs/gnuplot.gih
GNUPLOT_DRIVER_DIR=.
if [ "$1" = "-d" ] ; then
   GDB=gdb
   if [ -n "$2" ] ; then
     GDB="$GDB --args"
   fi
   GNUTERM=x11
   shift
fi
#export GNUTERM GNUHELP GNUPLOT_DRIVER_DIR
export GNUHELP GNUPLOT_DRIVER_DIR
if [ -n "$1" ] ; then
   PATH=.:$PATH GNUPLOT_LIB=../demo:../../demo $GDB ./gnuplot "$@"
else
   PATH=.:$PATH GNUPLOT_LIB=../demo:../../demo $GDB ./gnuplot
fi
=== end of file ===

This runs the fresh build of gnuplot without installing it first, 
referring to all new files.  The script is an extended version of how 
"make check" target in the demo subdirectory works.
