solaris 11 (i386), PIC, dlopen &c

Trying to build clisp with dynamic modules on solaris 11 (i386),
I get interesting errors with gnulib code:

1. dynmod/lib-rawsock.so (which does not use gnulib) is created
successfully and can be dynamically loaded.

2. dynmod/lib-wildcard.so cannot be created when clisp is configured

gcc -shared -Wl,-z -Wl,text -Wl,-h -Wl,lib-wildcard.so -o

3. when clisp is configured normally, dynmod/lib-wildcard.so is created
without an error, but loading is fails:
 (REQUIRE "wildcard") ==>
;; Loading file /.../dynmod/wildcard.lisp ...
;;  Loading module wildcard from /.../dynmod/lib-wildcard.so
  "ld.so.1: lisp.run: fatal: relocation error:
  file /.../dynmod/lib-wildcard.so: symbol rpl_mbsrtowcs:
  referenced symbol not found"

I am passing CFLAGS et al to the gnulib compilation, so "-fPIC -DPIC"
should have been used.

Bruno, do you have any insight on the matter?
