In my experience this all is done automatically:

- --------------------------------------------------
$ cd squidng
$ mv include/autoconf.h.in include/autoconf.h.in.playing-safe
$ autoheader
configure.in:919: warning: AC_TRY_RUN called without default to allow cross compiling
configure.in:1289: warning: AC_TRY_RUN called without default to allow cross compiling
$ cmp include/autoconf.h.in include/autoconf.h.in.playing-safe
$ echo $?
0
$ tail include/autoconf.h.in
#undef HAVE_LIBMALLOC

/* Define if you have the nsl library (-lnsl). */
#undef HAVE_LIBNSL

/* Define if you have the resolv library (-lresolv). */
#undef HAVE_LIBRESOLV

/* Define if you have the socket library (-lsocket). */
#undef HAVE_LIBSOCKET
- --------------------------------------------------
This is from `info autoconf':

       `autoheader' scans `configure.in' and figures out which C
    preprocessor symbols it might define. It copies comments and `#define'
    and `#undef' statements from a file called `acconfig.h', which comes
    with and is installed with Autoconf. It also uses a file called
    `acconfig.h' in the current directory, if present. If you `AC_DEFINE'

As for new options in configure.in you have to rerun autoheader and
autoconf to sync.
