Right. I think it's best, then, to let this thread die. There are 
already other threads where they need to be (unless someone wants to 
take this to libtool, but so far I'm not doing anything with libtool on 
NSK).

Right. I never said it was the *best* solution, just that 'zrldsrl' was 
the particular library needed. :-) (It took a while to dig up this 
information, so I figured it would be considerate of me to share those 
findings.) Anyway, thanks for enlightening me on autoconf syntax (which 
I would have gotten wrong :-)).

Well, from a (really) cursory comparison of the man pages, it looks the 
same...

At any rate, AFAICT gawk is not using libtool.
