	Untangle the last patch..  ap_add_version_component() needs to
	*prepend* the strings it's fed, not append them.  This is because
	the last thing that calls it before the string is locked is
	ap_set_version() (as in set-like-cement), which adds the
	SERVER_BASEVERSION, the platform (conditionally), and the
	SERVER_SUBVERSION (if defined) at a known location - the front
	of the string.

	This has the drawback that module contributions will be listed
	in reverse order from their 'importance' (which is, in turn,
	in reverse order from their appearance in the Configuration
	file ;-).  However, only modules with major effects should be
	contributing to the string anyway, so we can consider them
	equal.  Can't we?

	The alternative is to either allow ap_set_version() to directly
	modify the string rather than going through ap_add...(), or else
	to add another routine that appends rather than prepends.  I
	don't like either of these because of the issues with semantics
	synchronisation and code duplication.

	The last patch confused things, though, so I'm just returning the
	behaviour to the original design - if someone wants to take
	extra steps to have module contributions listed in the same
	order as they're called, have a party.

	This should fix Rasmus' problem with the components being out
	of order, although it doesn't touch his issue with the init
	callback duplicating the SERVER_SUBVERSION effort.

Fix the order of how the server_version string is built... All extra
components are tacked to the _end_ of the string. The front of the
server_version string is always SERVER_BASEVERSION. So if we have

    "Apache/1.3b7-dev (FreeBSD)"

 1. Add big fat hint in INSTALL about risks and to read the
    htdocs/manual/suexec.html document before using the suexec-related
    configure options.

 2. Make sure the user has at least provided one --suexec-xxxx option
    (specifies suEXEC parameters) in addition to --enable-suexec option.
    If only --enable-suexec is given APACI stops with a hint to INSTALL
    and htdocs/manual/suexec.html documents.

 3. Provide two additional --suexec-xxxx options to make the suEXEC
    configuration complete (especially for package maintainers who else
    had to patch the source tree) by providing ways to configure minimal
    UID/GID and safe PATH, too.

1. $(INCLUDES) on the linking (x.o -> x) step is bogus.
   This is only needed in the compile (x.c -> x.o) step
   and is already done in the implicit target .c.o

2. Because suexec.c now includes conf.h a "make suexec"
   is broken because we don't provide $(INCLUDES) for
   the all-in-one step (x.c -> x). So at least we have
   to provide the rule for suexec.o -> suexec.

configuration or htdocs files. This is similar to how APACI now works.
For the configuration files, the @@...@@ tokens are expanded, and
the file called conf\*.conf.default. Then it is _copied_ to the
corresponding conf\*.conf _only if_ that file does not exist. If it
does exist, it displays a messagebox saying "Preserving file XXX", like
APACI. [PR#2118]

For the htdocs, the manuals are always installed into htdocs\manual(*)
However htdocs\index.html and htdocs\apache_pb.gif are not installed
if they already exist. So this will now not overwrite the user's
index.html file. [PR#2084 -- for Unix, but applied to Win32 as well]
Note: under APACI the manuals are not installed if htdocs exists. On
Win32 htdocs\manuals is installed. This is because we add a menu
item "Apache Documentation" which launches explorer to read the docs, so
we really want them installed.

(* if the installation type includes manuals, that is).

A couple of other fixes:

  - always create cgi-bin and htdocs directories, even if the
    manuals are not being installed
