All `[u,]intXX.h` files should use `extern "C" { ... }` to allow linking with a C++ binding. I ran into this issue and worked it around by doing ```extern "C"...

ppx extension for literals

1

It would be nice to have a ppx extension which would provide a way to use literals. It is clumsy to write things like `Int32.of_string "0xffffffff"`

Provide pure-OCaml fall-back implementation

7

It would be nice if `stdint` had a fall-back on pure OCaml code for targets that don't support C bindings, e.g. Js_of_ocaml. I just open-sourced my pure OCaml integer implementation,...

Segfaults with 128-bit integers on Windows

17

With my colleague @msprotz, we observed segfaults related to 128-bit integers in some Windows OCaml programs using ocaml-stdint. It turns out that even the test executable produced by `make test/stdint_test`...

of_string for unsigned integers does not raise exception on negative inputs

**Actual behavior** Here is a toplevel session: ```shell μ> #require "stdint";; μ> "-1" |> Stdint.Uint128.of_string |> Stdint.Uint128.to_string;; - : string = "340282366920938463463374607431768211455" ``` Basically, this is the maximum 128-bit unsigned...

(Sorry, I accidentally hit enter) I'd like to propose some API for things like getting the most/least significant bit index, along with getting the number of set bits in an...
