R devel - Sep 2003 - configure problem in R-devel caused by conditionals

I re-generated configure of the latest R-devel with autoconf 2.57 and 
got the following problem:

configure: error: conditional "HAVE_ORBIT" was never defined.
Usually this means the macro was only invoked conditionally.

(resolving HAVE_ORBIT leaves us with HAVE_GNORBA causing the same 
problem. You should be able to reproduce it by running autoreconf (or 
aclocal; autoconf - not just autoconf!) and configure on the r-devel 
tree).

The culprit is primarily located in acinclude.m4, namely the macro 
GNOME_GNORBA_HOOK (used by GNOME_GNORBA_CHECK)
afaik it's never used in configure.ac (I couldn't find it at least), 
but the conditionals are "seen" by autoconf. Since all conditionals 
must be properly defined, it bails out.
(from automake docs: The shell condition (suitable for use in a shell 
if statement) is evaluated when configure is run.  Note that you must 
arrange for every AM_CONDITIONAL to be invoked *every* time configure 
is run - if AM_CONDITIONAL is run conditionally (e.g., in a shell if 
statement), then the result will confuse automake. )

Removing those macros from acinclude.m4 resolves the issue.

But, I'm wondering: in the m4 directory the README states that the 
files in m4 are used to create acinclude.m4 - is that done by hand or 
is there any "official" way to do it? There is no script called 
'bootstrap' in the root dir so the whole autoconf process seems to be 
non-standartized ... (ok, in the develper docs it says that one should 
simply run autoconf .. but then such issues as the above won't become 
visible as autoconf doesn't call aclocal, whereas e.g. autoreconf does 
...). So, how is the 'official' configure created?

configure --enable-maintainer-mode
make

and I think that is as `official' a way as any.  FWIW, autoconf works for 
me on 2.57.
