# The following makes sure that the include subdirectory is included,

# shell variable containing the absolute path to the top source
# directory (at least it's not documented), so we can't use that here.
# However, it does have a preset *ouput* variable. The following
# causes a literal '-I${top_srcdir}/include' to appear in the
# definition of the CONFIGURECPPFLAGS variable. The '${top_srcdir}'
# is then substituted by make. Unfortunately, this is somewhat
# broken: If we want to do further autoconf tests using this include,
# the '${top_srcdir}' either won't be substituted or it will be
# substituted with an empty string since there is no 'top_srcdir'
# shell variable defined by autoconf. TODO: figure out a way around
# this.
