Thanks Duane,
   What you have just written matched perfectly with my earlier reading
straight from the code. So I still can't see whats going wrong here.

yes:::

AC_ARG_WITH(cache-user,
[ --with-cache-user=USER System user account for squid permissions.
                          default: nobody],
[ if tets -z "$withval"; then
    AC_DEFINE(cfg_CACHE_EFFECTIVE_USER, "$withval", [change User for
squid to $withval])
  else
    AC_DEFINE(cfg_CACHE_EFFECTIVE_USER, "nobody", [default User for squid])
  fi
])
AC_SUBST(cfg_CACHE_EFFECTIVE_USER)

> - modify src/Makefile.am

yes:::
s%@DEFAULT_CACHE_EFFECTIVE_USER@%$(cfg_CACHE_EFFECTIVE_USER)%g;\

> - run bootstrap.sh (Makefile.am -> Makefile.in)

yes. it gives me ...
./src/Makefile.in: (looks OK)

cfg_CACHE_EFFECTIVE_USER = @cfg_CACHE_EFFECTIVE_USER@
...
s%@DEFAULT_CACHE_EFFECTIVE_USER@%$(cfg_DEFAULT_CACHE_EFFECTIVE_USER)%g;\

./configure: (looks OK)

# Check whether --with-cache-user was given.
if test "${with_cache_user+set}" = set; then
   withval=$with_cache_user; if test -z "$withval"; then
cat >>confdefs.h <<\_ACEOF
#define cfg_CACHE_EFFECTIVE_USER "$withval"
_ACEOF
   else
cat >>confdefs.h <<\_ACEOF
#define cfg_CACHE_EFFECTIVE_USER "nobody"
_ACEOF
   fi
fi

?? was done in Makefile.am, bootstrap did it for src/Makefile automatically.

yes:::
DEFAULT: @DEFAULT_CACHE_EFFECTIVE_USER@

> - run ./configure and test it..

yes, gives me ...
./src/Makefile:

cfg_CACHE_EFFECTIVE_USER =
...
s%@DEFAULT_CACHE_EFFECTIVE_USER@%$(cfg_CACHE_EFFECTIVE_USER)%g;\

And thats where I see the problem. Running make now will replace with ""
instead of "nobody" (default option wanted for this test)
