Subject: [PATCH] ruby: allow bindings to compile on Mac OS X
Date: Sun, 16 Nov 2014 21:48:26 +0100
Message-Id: <1416170906-23415-1-git-send-email-ll-notmuchmail@lange.nom.fr>
Precedence: list

On OS X, the library ends with .dylib (instead of .so). I also added
the .dll handling in any case.
Also, the flags '-Wl,--no-undefined' seems not accepted, so I excluded
them on OS X (only)
