Subject: compiler: Don't use __attribute__ for non-GCC compilers.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4380e924b27fb8528e1c50ebfb4dab4d76f9601d;p=openvswitch

compiler: Don't use __attribute__ for non-GCC compilers.

__attribute__ is a GCC feature that we should not expose to other
compilers.
