[Crosstoolchain-logs] [device-tree-compiler] 34/58: Clean up gcc attributes

[Vagrant Cascadian]

This is an automated email from the git hooks/post-receive script.

vagrant pushed a commit to branch debian/master
in repository device-tree-compiler.

commit 672ac09ea04d998dfddfdef3070a8af8d480182b
Author: David Gibson <david at gibson.dropbear.id.au>
Date:   Mon Mar 6 12:06:15 2017 +1100

    Clean up gcc attributes
    
    We have a number of explicit __GNUC__ conditionals to tell if we want to
    use some gcc extensions for extra warnings.  This cleans this up to use
    a single conditional, defining convenience macros for those attributes.
