Bruno,

as I noted before, building 64-bit binaries on Solaris is not unsupported by 
gcc. It is very normal.

The issue was resolved by Ralf Wildenhues, who is a libtool developer.

I had configured iconv using

CC=gcc
CFLAGS=-m64

if instead one uses

CC="gcc -m64"

so iconv builds fine 64-bit on Solaris 10 x86 and OpenSolaris on x86.

You might want to add that to your documentation.

The strange thing is, this builds 64-bit on more recent OpenSolaris and Solaris 
releases with just setting CFLAGS.
