It's legal to do

[target.cfg(target_os = "linux").dependencies]
x11 = { version = "2.3.0", features = ["xlib"] }

and that would allow us to remove all of these duplicate entries, I'm pretty sure.

[fabricedesre]

Cool, i'll try that. And maybe I'll update all the other repos where I added the armv7 section...

[emilio]

Looks good, also needs a version bump :P

I'd prefer to use the cfg() syntax, but if it's blocking or something I can merge it right away and do the changes myself.

lib.rs uses cfg(target_os="linux") and cfg(target_os="macos"). ("unix" applies to both.)

[emilio]

Y es, xlib should not be used on Marcos Mac OS.

[fabricedesre]

Updated, sorry.

LGTM, will merge and publish after the travis run :)

Actually don't be sorry, thanks for doing this :)
