It occurs to me that I needed something like this in m4-1.5.  I have some 
common builtins which need to be compiled into the binary, and some 
occasional (or post-compile) modules which define additional builtins.  In 
the end I compiled all the modules with libtool, bu dlpreopened the standard 
builtins causing the static component of the libtool library to be linked 
into the binary.

This technique has the added advantage of using the same API in the main 
module whether (lt_dl)opening the default startup commands or (lt_dl)opening 
user's add on modules compiled outside the source tree.  I found that I could 
remove whole swathes of code to deal with special startup procedure loading 
when I did this.

Just tossing it in the air incase you find it useful.

Cheers,
        Gary.
