4Subject: [PATCH] tlshd: configure.ac: Use AC_CHECK_HEADER instead of
5 AC_CHECK_FILE
6
7AC_CHECK_FILE doesn't work when cross-compiling [1], which breaks a lot of
8use cases (like OpenEmbedded for one). Autoconf supports AC_CHECK_HEADER
9which can be used instead and is more robust [2] so let's use that
10instead.
