R-2.1.0 fails to compile on the newest release of FreeBSD,
complaining about
undefined references to __builtin_alloca. On FreeBSD, alloca()

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:
mkdir ../../../../library/grDevices/libs

mkdir ../../../library/graphics/demo
mkdir ../../../library/graphics/po

Did you run a new, clean build? From the output it seems as if you
just changed the file in your old build and typed make - obviously
that doesn't help at all, because the setting must the changed
*before* you start building. So if you didn't do so, please remove
the build, unpack the sources again, run configure, change the ALLOCA
define and then build.
Cheers,
Simon
