------- Comment #1 from jakub at gcc dot gnu dot org 2009-01-06 15:29 ------- http://gcc.gnu.org/install/specific.html#sparc-sun-solaris2 documents that you need to configure with --disable-multilib in this case, perhaps just this should be repeated also for i?86-sun-solaris2 or moved into *-sun-solaris2 section.
