--- Comment #3 from Rainer Orth <ro at gcc dot gnu.org> --- Now that -mgeneral-regs-only is only passed on targets that support it, the failure mode on Solaris/SPARC is the same as on Solaris/x86: Excess errors: Undefined first referenced symbol in file __cyg_profile_func_exit /var/tmp//cc8rdHRb.o __cyg_profile_func_enter /var/tmp//cc8rdHRb.o ld: fatal: symbol referencing errors Please fix: this has been ignored for 6 weeks now.
