Compilation broken on Windows

[murmour]

This is what I get when doing opam install re with the official installer:

I had to pin re.1.5.0, which has no build issues.

[rgrinberg]

Hmm, this seems like an oasis issue. We probably upgraded oasis between 1.5.0 and the current version.

[murmour]

Then a hotfix would be to regenerate the build system using an earlier version of OASIS. I can't suggest a particular version though. Um, the one that was used in 1.5.0?

[murmour]

re.1.6.1 doesn't compile either -- same error.

Hi !

I got this problem when installing re.1.7.1 :

[ERROR] The compilation of re failed at "ocaml setup.ml -configure --prefix C:/cygwin64/home/ME/.opam/4.03.0+mingw64".

I didn't install it directly but through the installation of user-setup 0.6

@TheHaricover Your setup is wrong, you probably have several incompatible version of OCaml installed.

How do I found out if this is true ? I just need to uninstall OCaml and reinstall it ?
