    scm_make_gsubr (s_ ## scm_acons,  3,  0,  0, (SCM (*)()) scm_acons); 

   configure options as follows:

   export LIBRARY_PATH=/sw/lib
   export CPPFLAGS=-no-cpp-precomp
   export CPATH=/sw/include
   ./configure --prefix=/sw --infodir=/sw/share/info

on first glance, the CPPFLAGS looks suspicious.  the ## is supposed to
"glue" the tokens surrounding it together producing a single identifier,
in this case `s_scm_acons', during the C preprocessing pass.  thus
options that disable (or otherwise inhibit normal operation) of the C
preprocessor are questionable.  what happens when you configure without
setting CPPFLAGS?  (why is it necessary to set it?)

   and the configure output: [...]

ok, i'll save this to compare w/ the non-CPPFLAGS output (unless we get
lucky and things magically work w/o further investigation :-).
