(amd64-sol2-tdep.o): Add dependencies. * amd64-sol2-tdep.c, config/i386/sol2-64.mh, config/i386/sol2-64.mt: New files. * i386-sol2-nat.c (amd64_sol2_gregset64_reg_offset, amd64_sol2_gregset32_reg_offset, _initialize_amd64_sol2_nat): New. (supply_gregset): Correct order of arguments to amd64_supply_native_gregset. (fill_gregset): Correct order of arguments to amd64_collect_native_gregset. * configure.host (i[34567]86-*-solaris2.1[0-9]*): Add new case. * configure.tgt (i[34567]86-*-solaris2.1[0-9]*): Likewise. * configure.in (*-*-solaris2.[[6789]]): Add *-*-solaris2.1[[0-9]] for definition of NEW_PROC_API. * configure: Regenerate.
