Subject: [PATCH] ocaml: Replace old enter/leave_blocking_section calls
|
|
|
|
Since OCaml 4 the old and confusing caml_enter_blocking_section and
|
|
caml_leave_blocking_section calls have been replaced with
|
|
caml_release_runtime_system and caml_acquire_runtime_system (in that
|
|
order). Use the new names.
|
|
|
|
(cherry picked from commit 7e1d7c1330185a1f3da2ce2100f59637518c3302)
