One first reaction to your suggestions.

R-2.1.0 fails to compile on the newest release of FreeBSD, complaining about
undefined references to __builtin_alloca. On FreeBSD, alloca() is declared in
stdlib.h, not alloca.h as the R sources expect. Therefore, HAVE_DECL_ALLOCA
does not get set, so the R sources declare alloca() after it has already been
#defined by stdlib.h.
A possible fix is to modify the configure script to look for the declaration of
alloca() in stdlib.h (perhaps after it fails to find it in alloca.h).
It is already supposed to, so it is not finding the declaration there
either. If you look up the definition of
AC_CHECK_DECLS([alloca], , , [#include <alloca.h>])
it searches in stdlib.h. Can you please send us the appropriate part of
config.log? It may be that this is failing because alloca.h is not found
(but AC_FUNC_ALLOCA is making the same assumptions).
Perhaps the easiest way out is to override the setting on FreeBSD: can
you please confirm that manually changing
#define HAVE_DECL_ALLOCA 1
in config.h works?
Changing "#define HAVE_DECL_ALLOCA" to 1
in line 81 of R-2.1.0/src/include/config.h
gives me the following stopping:

Because I have almost no skills in C, automake and autoconf I have no
idea on how to go on, sorry.
Hopefully Eric makes considerable progress ...
