I do believe that functions are now okay for the 21st century auto*.
'bout time.

------------------------------------------------------
autogen version 5.5.4
guile version 1.4.1

Necessary to:

regenerate fixinc/fixincl.x from
   fixinc/inclhack.def and fixinc/*.tpl
run the fixinc/ directory make check
regenerate the top level Makefile.am's from
   Makefile.tpl and Makefile.def

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

(you could probably get away with earlier versions than
5.5.4, but the Makefile.tpl could contain some of the feature
creep since fixincl.tpl was written...Makefile.tpl is also
under active development.)

At some point, Guile 1.6 will be required because they are
in the process of disposing of the gh_* interface.  AutoGen
currently uses that.

And, no, AutoGen is not part of Guile, nor does AutoGen
ship with Guile.  You gotta get both.
