--- Comment #6 from Ian Lance Taylor <ian at airs dot com> --- Re: comment #5. This bug report is about Solaris/x86 and is specific to Solaris. If you want to report a bug on any other target, please open a different bug. Thanks. In your case I suspect you need to use the configure option --with-arch-32=i686.
