sys-power/powertop/files/powertop-1.98-gcc-4.7.patch

From b86877fb2f24563d74cd3faf7eceffcc8fa59299 Mon Sep 17 00:00:00 2001

Subject: [PATCH] include unistd.h when necessary

Older versions of gcc (pre-4.7) would implicitly include unistd.h in some
of its internal headers.  With newer versions though, that is no longer
the case, so building powertop breaks with files that use things from the
unistd.h header but don't include it explicitly.
