Either libtool somehow did not infer the right option for your GCC to produce
position-independent code (i.e. code without relocations in the .text segment).
Or your GCC is broken.

I would try to rebuild with CC="gcc -fPIC". If that succeeds, then libtool
guessed the wrong option. If not, your GCC is unusable.

This matches the recommendations given in
  <http://gcc.gnu.org/install/specific.html#ix86-x-solaris210>.
Good.

Other than the suggestion above, I would suggest using a different compiler or
GCC version. Why not just use /usr/bin/cc or /usr/bin/gcc? That is certainly
well tested. A libiconv built by any C compiler is usable by any other C
compiler.

In this thread:
<https://de.opensolaris.org/jive/thread.jspa?threadID=116065&tstart=143>
a person with a similar name as yours reports that GCC 4.5.0 prereleases went
well. Now gcc 4.5.0 is released.

Thanks for the offer, but I feel that finding out about the correct
configuration options for GCC on OpenSolaris would distract me a bit from my
main development goals.
