I tried manually editing the build line in the `.opam/repo/default/packages/conf-gmp/conf-gmp.1/opam` file, but it's still using the old command.\r\n\r\nAlso, I tried updating my opam to see if version 1.1 was available for my OPAM (1.2.2, installed with Protzenko's Ocaml for Windows installer, OCaml 4.02.3), but no other version was found."}}
