When I configure with --disable-multilibs on mips-sgi-irix6.5, I still get a multilibbed target libiberty built (mips-sgi-irix6.5/64/libiberty). This is with both 4.0 and 4.1 cvs of 20050317.
This would cause a bootstrap failure if the multilib is not supported by the host. -- Summary: target libiberty multilibs built with configure -- disable-multilibs Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: other AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: billingd at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: mips-sgi-irix6.5 GCC host triplet: mips-sgi-irix6.5 GCC target triplet: mips-sgi-irix6.5 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20510
