Let's start a flame war about (X)Emacs! ;-)

Sure.

Cool :).

Okay, what about this (I'm writing .texi the first time...):

 If a given @var{dir} is not found, no error is reported, so a
 @code{configure} script can configure whichever parts of a large source
-tree are present.  If a given @var{dir} contains @file{configure.in} but
-no @code{configure}, the Cygnus @code{configure} script found by
+tree are present.  If a given @var{dir} contains @code{configure.gnu}, it is 
run
+instead of @code{configure}. This is for packages that might use a
+non-autoconf script @code{Configure}, which can't be called through a
+wrapper @code{configure} since it would be the same file on case-insensitive
+filesystems. Likewise, if a @var{dir} contains @file{configure.in} but no
address@hidden, the Cygnus @code{configure} script found by
 @code{AC_CONFIG_AUXDIR} is used.
 
 The subdirectory @code{configure} scripts are given the same command

Yours, Rüdiger.
