%{exe}% expands to .exe on Windows platforms, and the empty string on
other systems, allowing .install files to be generated correctly.

Script attempted to write a filename with "?" in it, which is illegal on Windows. "Fixed" by using a dummy name for the download (since the file is only downloaded to obtain its checksum). Signed-off-by: David Allsopp <david.allsopp@metastack.com>

Two problems from the Jbuilder upgrade: 1. opam_admin_top.cmi should be installed 2. Opam_admin_top functions were not available, because Topmain was invoked from within Opam_admin_top. Signed-off-by: David Allsopp <david.allsopp@metastack.com>
The repository upgrade automatically adds a dependency on the ocaml package (i.e. the compiler) if none are inferred (through ocaml-version translation, etc.). This is a nuisance if running opam admin upgrade for a second time (e.g. because some older package definitions have been imported) where you have packages which intentionally do not depend on the compiler. Process tweaked so that if the opam file already has opam-version: 2.0, then the automatic dependency is not added. Signed-off-by: David Allsopp <david.allsopp@metastack.com>

Shedding the weight of some simpler commits:
opam-admin.top- prior to Jbuilder, this was built usingocamlmktop. I converted this badly, because the existing code now works as a toplevel, but you can't run a script by having#!opam-admin.toporopam-admin.top foo.ml. The commit generates thelet _ = Topmain.main ()in a second file which is used to createopam-admin.topand the actualopam_admin_top.mlis now used to generate a library. This means that scripts have two choices - you can either#require "opam-admin.top"in your script, or you can run an.mlfile withopam_admin_top(although you needopam_admin_top.cmiin the same directory as your script).%{exe}%does exactly what it says on the tin. The main reason for making it a global is to standardise the name used (so there's no temptation for%{ext_exe}%, etc. This extension is intentionally blank on Cygwin because Cygwin has its own official handling for automatically adding.exe.ocamldependency kept getting re-added after I'd manually removed it... this legacy commit doesn't do that if theopam-versionof the file is already2.0. The principle may be useful in the future...opam admin upgradewas an attempt to download URLs using their filename. Fine for a lot of things, but troublesome on Windows when you start having?characters, etc., so this patch downloads patches and other referenced files using a safe filename (it's only to compute their checksums).sys-ocaml-arch,sys-ocaml-libcandsys-ocaml-ccto allow accurate selection of the system compiler on Windows (this may prove unnecessary with the other work we've been looking into on switch parameters, but I don't think these variables would ever do any harm in future).
