Comment (by ryandesign@…):

 Here is a patch to update the autogen port to 5.18.3. It does not build
 for me:

 {{{

 In file included from ./autogen.h:60:
 In file included from /opt/local/include/libguile.h:33:
 In file included from /opt/local/include/libguile/async.h:26:

                                               ^
 }}}

 The problem seems to be that guile's headers use `noreturn` as an argument
 name in a function, but autogen `#define`s `noreturn` to something else.
 Perhaps autogen 5.18.3 is designed for a newer version of guile. Our
 ticket to update the guile port is #29307.
