Hi,

[Upstream Cc-ed.]

Please enhance AC_DEFINE_DIR, and apply this patch:

----------------------

(patch against Miscellaneous/ac_define_dir.m4 as found in
ac-archive-0.5.51.tar.gz )

This makes available the variables not only as C preprocessor symbols,
but also as output variables, so that files in AC_CONFIG_FILES get their
variables like @PROG_PATH@ expanded.

Bye,

Joost
