gcc (GCC) 9.2.0 complains:
xentoollog_stubs.c: In function ‘stub_xtl_ocaml_vmessage’:
xentoollog_stubs.c:93:16: error: initialization discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
93 | value *func = caml_named_value(xtl->vmessage_cb) ;
| ^~~~~~~~~~~~~~~~
This patch constifies the pointer returned by caml_named_value in order
to the accommodate newer versions of OCaml.
In OCaml >= 4.09 the return value pointer of caml_named_value is
declared const.
