With httpd 1.3, there used to be a way to build something what was
called "shared core", a shared object that contained the server in a
form you could link it into an application.

I don't know if this is still possible with httpd 2.x, but what used I
in an RPM package at the time was 

    --enable-rule=SHARED_CORE
    
    mkdir shared_core
    cp -p src/libhttpd.ep src/libhttpd.so src/httpd
    shared_core


   # install shared-core apache
   install -m 755 shared_core/libhttpd.ep $RPM_BUILD_ROOT/%{_libdir}/%{name}
   install -m 755 shared_core/libhttpd.so $RPM_BUILD_ROOT/%{_libdir}/%{name}
   ln -s %{_libdir}/%{name}/libhttpd.ep 
$RPM_BUILD_ROOT/%{_sbindir}/httpd-shared_core
   ln -s %{_libdir}/%{name}/libhttpd.so $RPM_BUILD_ROOT/%{_libdir}/libhttpd.so


At the time, that was reportedly working to build DSOs with Kylix 3.
