this is bad.
as I explained, the modules/syscalls directory should be buildable
using a pre-installed clisp, i.e., I must be able to redirect
build-aux references to, say, /usr/share/clisp/build-aux/

I already have CL_MODULE_COMMON_CHECKS() in clisp/modules/syscalls/configure.in
which expands to
AC_REQUIRE([AC_CONFIG_AUX_DIR],
[AC_CONFIG_AUX_DIR([$cl_cv_clisp_libdir/build-aux])])

PS. Bruno, sorry about 2 copies, I hit "reply" instead of "reply-to-all" first
