after the inclusion of configure.host, the value of cpu_include_dir is
printed by configure, although the comment in configure
# Propagate the target-specific source directories through the build chain.
# (Nothing currently uses cpu_include_dir directly; only atomicity_include_dir
# uses it, and it only gets used in this file.)
says otherwise. The test in acinclude.m4 uses it:
dnl
dnl Check to see what architecture and operating system we are compiling
dnl for. Also, if architecture- or OS-specific flags are required for
dnl compilation, pick them up here.
dnl
AC_DEFUN([GLIBCXX_CHECK_HOST], [
. $glibcxx_srcdir/configure.host
AC_MSG_NOTICE([CPU config directory is $cpu_include_dir])
AC_MSG_NOTICE([OS config directory is $os_include_dir])
])
either cpu_include_dir should be updated in configure.host or the
message be changed.
