need script to install Apache DSOs?

[Jeff Trawick <tr...@attglobal.net>]

On some platforms, we get some unexpected names for DSO files because
of the way libtool works.

While normally we expect mod_foo.so...

Tru64:   libmod_foo.so
AIX:     libmod_foo.a(libmod_foo.so.0)  
         (not just a name change; archive library is used)
HP-UX:   mod_foo.sl

What if we had a DSO installer which normally called
libool --mode=install but on some platforms did something special?
"make install" would need to use this for DSOs and apxs would need to
use this as well.

If we stick with the expected mod_foo.so usage we don't have to hack
up our docs or tweak the LoadModule statements we generate from apxs
or make install.

Comments, concerns?

[PATCH] script to install Apache DSOs

With the new shell script in this patch, we have a place to fix-up
libtool-isms so that the normal LoadModule statement works.  This
version of the script fixes up the install on AIX, HP-UX, and Tru64.

Beyond the function in this patch, the next step is to have it
installed in prefix/build and teach apxs to use instdso when it
installs DSOs.

I have only tested this on AIX thus far.  I hesitate to test it much
further before people have a chance to comment on things they might
not like.

Have fun...
