How fun!  ;-)

Anyway, sorry for all the mess that you ended up merging.

Done.

Fixed (I had a dangling copy of the `modules' directory at the top-level
which is why I hadn't noticed it.  Sigh.).

Done.

Done.

I think I routinely hit "Update all nodes" in Emacs, hence those
changes.  Sorry.

That's from `guile.m4' from Guile 1.8 which should be available at
`/usr/share/aclocal' (or similar).  It's only needed by those who modify
`configure.in'.  Should we really include it?


The changes above are available in my repository.

There are still a couple of minor glitches:

  * Code in `guile/src' doesn't want to be compiled with
    `-Wstrict-prototypes'.  Since adding `-Wno-strict-prototypes'
    doesn't annul the effect of `-Wstrict-prototypes', I'm afraid we'll
    have to remove `-Wstrict-prototypes' at the project level (i.e, in
    `configure.in'), and add it to `CFLAGS' in sub-directories where it
    makes sense.

  * The "function index" of the manual mixes Scheme procedures and C
    functions.  In theory it might be possible to create separate
    indices but since `@deffn' automatically adds functions to the
    function index, it would not be convenient.


For some reason, `make' now fails here in `doc/reference':

  $ make -C doc/reference/
  make: Entering directory `/home/ludo/src/gnutls/doc/reference'
  gtk-doc: Scanning header files
  [...]
  gtk-doc: Compiling scanner
  gnutls-scan.c:5:25: error: glib-object.h: No such file or directory
  [...]

Clearly, it lacks `pkg-config glib-2.0 --cflags` as CFLAGS.
Unfortunately, I wasn't able to pinpoint the root of the problem.
Re-running `autoreconf' and `configure' didn't help.  Any hint?

Thanks,
Ludovic.
