Subject: Make check-installed-headers.sh ignore sys/sysctl.h for x32
Date: Thu, 03 Nov 2016 22:48:00 -0000 [thread overview]
Message-ID: <alpine.DEB.2.20.1611032248050.20687@digraph.polyomino.org.uk> (raw)
check-installed-headers tests were failing for x32 because of the x86
bits/sysctl.h containing a #error for x32. This patch makes the tests
ignore sys/sysctl.h for x32, similar to the other special-casing of
particular headers.
Tested for x86_64 (full testing for -m64, compile-only for x32).
