Subject: m4: Fix ./configure --disable-ocaml
From: Richard W.M. Jones rjones@redhat.com Wed Jul 20 09:23:37 2022 +0100

OCaml is required to compile libguestfs, however we should still be
able to disable the OCaml bindings.  This didn't work because using
--disable-ocaml caused various configure tests to be skipped which are
required to compile the daemon.  In particular the check for
caml_alloc_initialized_string, resulting in this error:

pcre-c.c:47:1: error: static declaration of ‘caml_alloc_initialized_string’ follows non-static declaration
 caml_alloc_initialized_string (mlsize_t len, const char *p)
 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Also OCaml gettext is not required by libguestfs.  There are no *.ml
files used by libguestfs which require translation.
