BTW: I received SIGBUS all the time in dlopen() and after wasting
     a lot of time debugging this problem I discovered that SunOS
     doesn't like it when the mod_xx.so files are stripped on
     installation. So, never strip them on SunOS.

two reasons:

- LDFLAGS has traditionally meant "flags to use when linking an
    executable", and such flags can be different than those for making
    a shared library

- LDFLAGS has traditionally been flags supplied to the cc executable for
    linking, not flags supplied to the ld executable... cc translates
    various flags before passing them to ld.  For example,
    "gcc -Wl,M" passes -M to ld.

eventually.  signals are a mess.  It's bogus for mod_include to be
doing a hard_timeout() and then running subrequests and all that other
fun stuff.

----------------------------------

mod_so now keeps track itself of which modules are actually loaded and which
are not by remembering both the module pointer and the module name. This fixes
two problems:

1. Because our server configuration is read twice the modules
   were loaded twice which is both not needed and leads to confusion later on
   unload because the OS-internal load counter increases. Then on unload the
   module pointer was removed from the Apache core structure on the first
   unloads but (because of the load counter) the modules were removed later.
   Although this worked, it was very ugly. The only consequence is that we now
   keep track of loaded modules ourself and don't rely on the dynamic loader
   of the platform. This now also avoids multiply tries to unload an already
   unloaded module and thus removes harmless but irritating error_log entries
   ``[error] Cannot remove module mod_setenvif.c: not found in module list''.
   as shown below.

2. Because we now keep track of the module names we used on loading we now can
   give correct corresponding log messages even on unloading.

To illustrate the change, here is the old error_log:
(the first unloads correspond to the first loads which
 are printed on stderr unless mod_log_config is present)

-------------------------------------------------

1. Shared object support is compiler-dependend, so we have to
   move the XXX_SHLIB stuff _after_ the compiler checks in
   the Configure script.

3. Added entries for manual/custom shared object support to
   Configuration.tmpl file, so the user knows what he has to do.
   Configure already supported this in the past but nothing was
   documented here.

3. Added initial support for Solaris 2.x.

4. I've now tested shared object support under the following
   platform/compiler combinations:
      - FreeBSD 2.1.5 with gcc 2.8.0
      - Debian 1.3.1  with gcc 2.7.2
      - Solaris 2.6   with gcc 2.7.2
      - Solaris 2.5.1 with gcc 2.7.2
      - Solaris 2.5.1 with WorkShop Compilers 4.2 30 Oct 1996 C 4.2

   All ran out-the-box with my test procedure:
   [Yes, I really would like to see my configure stuff added...]
      $ gunzip <apache-1.3b6-dev.tar.gz
      $ cd apache-1.3b6-dev
      $ ./configure --prefix=/tmp/apache --enable-shared=max
      $ make
      $ make install
      $ /tmp/apache/sbin/apachectl start
      $ lynx -mime_header -source http://localhost:80/

configure time without interfering with other modules doing the same. It
is used like this in .module files or CONFIG_START/END sections:

 SUBVERSION="$SUBVERSION mymodule/123"

At present multiple modules adding themselves to the version string get
confused, causing compile warnings and ending up with only one module in
the version. Module authors using -DSERVER_SUBVERSION in their $CFLAGS
will have to make a slight modification to the above format instead. This
will only affect modules designed for 1.3 betas.

1. move generation of ap_config.h to a later point in the script
   because else it doesn't pick up HIDE or STATUS correctly.

2. change the generation of shared objects from explicit rules to
   implicit rules: First the $< is only portable for implict
   rules (e.g. FreeBSD's make fails) and second we already build
   .o's implicitly, so we should do with .so's the same way.
