Not on that target.

I'm afraid to say you are mistaken

http://gcc.gnu.org/install/specific.html#ix86-x-solaris210

GCC builds 64-bit applications fine on Solaris. It supports the "-m64" flag to 
make 64-bit binaries.

I have now managed to build iconv 64-bit on Solaris x86, though that was with 
the aid of Ralf Wildenhues, a libtool developer. He told me what commands to run 
manually, and the library built.

I think Ralf might concede this is a libtool bug, and since iconv uses libtool, 
the bug come from there. But I will let Ralf comment on that. (I've cc'ed Ralf).

I am trying to get Ralf an account on a Solaris x86 machine, but for some reason 
this has taken longer than I expected.

Hopefully, if what I believe is a libtool bug is fixed, and you could use a 
later version of libtool, it should be possible to get this to work.
