-Subject: [PATCH] configure.in: tighten AIX test
-
-Depending on the configuration, the cpp output may contain the string 'yes'
-in a comment if built under a path containing 'yes', confusing the _AIX
-test:
-
-${CROSS}-cpp conftest.h
-\# 1 "conftest.h"
-\# 1 "<built-in>"
-\# 1 "<command-line>"
-\# 31 "<command-line>"
-\# 1 "/home/peko/source/buildroot/output-yes/host/x86_64-buildroot-linux-gnu/sysroot/usr/include/stdc-predef.h" 1 3 4
-\# 32 "<command-line>" 2
-\# 1 "conftest.txt"
-
-Fix it by only matching on 'yes' on a line by itself.
