Subject: Add -Wpointer-arith to compiler flags.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ad8d3e6bdf9c2f962d698e6836ae9bc69bd464cc;p=openvswitch

Add -Wpointer-arith to compiler flags.

This should help us to avoid doing pointer arithmetic on void * pointers,
which is a GCC extension that other compilers do not support.
