Right, AC_FUNC_ALLOCA already defines HAVE_ALLOCA_H as a preprocessor
macro, under the same conditions. But we have the habit, when we
create a .h file from a .in.h file, to substitute values found at
configure time directly. This
  - makes it possible to reference the same variables in the
    module description,
  - increases the probability that the .h file works even when the
    user has forgotten to #include <config.h> or adds or removes
    a macro definition through #define or #undef,
  - increases transparency in case of a compilation error.

Pushed.
