Yes, that's true! I made already years, or so, ago another change to  
my compile script, when I found that a subsequent re-compilation  
produced something strange: I added a 'make clean' to start the whole  
process with, i.e. before configure is invoked.

My assumption was that the inherent configure step completely  
overwrites src/epaths.h, so that I don't need to take care whether  
there is a patched version lying around. This does not seem to be  
true, because I might have observed it in a cleaned environment, so  
your correction should be put into the compile script. A bit  
modified, because when src/epaths.h-orig exists another change might  
not be necessary (/might/, because a user could decide to try another  
local lisp path), from the old

     (cd src; mv epaths.h epaths.h-orig; \
        printf "s,\(#define PATH_LOADSEARCH \"\),\\\1%s:,\n" "$ 
{locallisppath}" > locallisppath.sed; \
        cat epaths.h-orig | sed -f locallisppath.sed > epaths.h; rm  
locallisppath.sed)

to newer

     (cd src
	if [ -r epaths.h-orig ]; then
	    echo "### src/epaths.h-orig already exists, no further change ###"
	else
	    mv epaths.h epaths.h-orig
	    printf "s,\(#define PATH_LOADSEARCH \"\),\\\1%s:,\n" "$ 
{locallisppath}" > locallisppath.sed
	    cat epaths.h-orig | sed -f locallisppath.sed > epaths.h
	    rm locallisppath.sed
	fi)

And 'make *clean' need to remove src/epath.h-orig!

The actual problem is that the system conforming local lisp path in  
Mac OS X is /Library/Application Support/Emacs, a path name with a  
space. This character needs to be saved when passed within the  
argument to the configure script, and it needs to be recognised as  
part of the path name and not a separator by configure. I have no  
solution, only this work-around ...
