dnl Version 2.55 of autoconf generate code that assume a
dnl sub directory isn't a link. Internally at Ericsson
dnl some OTP application directories are soft links.
dnl An added "/." solves this problem.

dnl The arguments to AC_CONFIG_SUBDIRS should be literals
dnl but a bug in autoconf 2.13 breaks conditional use
dnl of multiple AC_CONFIG_SUBDIRS so we do it the "wrong"
dnl way to force correct code.
