`ocamlmklib` supports some but not all linker flags. we have some `LDFLAGS` that are not supported by `ocamlmklib`, so they need to be passed via `-ldopt`. this PR prepends `-ldopt` to each word in `LIBS` (which is set to `LDFLAGS` in ./configure).
Add functions to generate integers pseudo-randomly
Add fast path when extraction leads to intnat
pass LDFLAGS to ocamlmklib via -ldopt
…es added by configure
It looks like `-native` causes `ocamldep` to produce insufficient dependencies for a bytecode + native build like we need to do. See log at https://881129.bugs.gentoo.org/attachment.cgi?id=832035
The build uses ocamlc to compile C files, so it's more reliable to test C compilation and linking using $ocamlc than using $cc. Also: add .gitattributes for Windows Co-authored-by: Xavier Leroy <xavier.leroy@college-de-france.fr>
With the flambda variants of the ocaml compiler, compilation failed with `Error (warning 58 [no-cmx-file]): no cmx file was found in path for module Zarith_version, and its interface was not compiled with -opaque`
When testing for the availability of a library, don't pass compilation flags to the linker: they are not relevant and flexdll may not recognize them. Co-authored-by: Hugo Heuzard <hugo.heuzard@nomadic-labs.com>
We no longer need it to select between assembly files.
This works better on Mac with Homebrew, for example. Fall back to the old method if pkg-config is not available or doesn't work.
Namely: - Whether GMP was found from pkg-config - Which C includes were selected (in summary of configuration)
Some simplifications and improvements to the configure script

This patch improves the bounds used in of_float to decide whether the double can fit into an OCaml 63-bit tagged int. The upper bound is 0x3ffffffffffffe00, which is exactly representable as a double (2^53-1)*2^9 = (2-2^-52) * 2^61 as it is 1.1...1 * 2^61 with 52 ones after the 1, and is less than 2^62, so it is representable as an OCaml int. The double just after 0x3ffffffffffffe00 is 0x4000000000000000, or 2^62, which does not fit an OCaml int. For the lower bound, -0x4000000000000000 is exactly representable as a double, but also the smallest number that fits an OCaml int.

Zarithv1.13config.guesswhich was removed from Zarith upstream.duniverse-v1.13as well, but I don't think I can set that.
