Not quite, I'm afraid:

----
libtool: link: mv -f ".libs/libfoo.expT" ".libs/libfoo.exp"
libtool: link: cc -Z -Wl,+h -Wl,libfoo.sl -Wl,+b -Wl,/tmp/project/lib -o 
.libs/libfoo.sl  .libs/xxjni.o .libs/mcatobj.o   -L/opt/lib/pic -L/opt/lib 
/opt/lib/pic/libxxlib.a -L/opt/lib /opt/lib/libxml2.a -lz /opt/lib/libiodbc.a 
/opt/lib/libiodbcinst.a -lcl -lpthread /opt/lib/libpcre.a -lm -lc  +DA2.0
/usr/ccs/bin/ld: Unsatisfied symbols:
   main (Not referenced yet! Probably due to -u option)
*** Error exit code 1
----

(Besides, according to the cc(1) man page, all -Z does is allow the 
dereferencing of null pointers...)

I remember working around this in 1.5.x by hacking the Libtool 
configure-script section to choose the hpux10* commands instead of hpux11*. 
(The former uses "ld -b ...", which works on this system.) This hack still 
seems to do the trick, so that would seem to be the appropriate fallback.


Many thanks for your fine work,
