abs_top_srcdir broken?

[Sébastien Hinderer]

Dear all,

Given the follwing configure.ac script:

AC_INIT([demo], [demo], [0.1], [demo@demo.org])
AC_MSG_NOTICE([abs_top_srcdir="$abs_top_srcdir"])

Tue configure script produced by autoconf 2.69 prints:

configure: abs_top_srcdir=""

Is that an expected behaviour?

Thanks,

Sébastien.
