re PR target/21275 (gcc 4.0.0 crash with mingw when using stdout in global var)
PR middle-end/21275 PR middle-end/21766 * target.h (struct gcc_target): Add valid_dllimport_attribute_p target hook. (struct cxx): Add adjust_class_at_definition target hook. * target-def.h: (TARGET_VALID_DLLIMPORT_ATTRIBUTE_P): New define, defaulting to hook_bool_tree_true. Add to TARGET_INITIALIZER (TARGET_CXX_ADJUST_CLASS_AT_DEFINITION): New define, defaulting to hook_void_tree. Add to TARGET_CXX. * tree.h (struct decl_with_vis): Rename non_addr_const_p field to dllimport_flag. (DECL_NON_ADDR_CONSTANT_P): Replace with DECL_DLLIMPORT_P macro. * tree.c (merge_dllimport_decl_attributes): Check DECL_DLLIMPORT_P instead of attribute. Check for dllexport override. Warn if inconsistent dll linkage. Don't lose old dllimport if decl has had address referenced. Tweak lookup of dllimport atribute. (handle_dll_attribute): Check targetm.valid_dllimport_attribute_p for target specific rules. Don't add dllimport attribute if DECL_DECLARED_INLINE_P. Set DECL_DLLIMPORT_P when adding dllimport attribute. (staticp): Replace DECL_NON_ADDR_CONSTANT_P with DECL_DLLIMPORT_P. * varasm.c (initializer_constant_valid_p): Replace DECL_NON_ADDR_CONSTANT_P with DECL_DLLIMPORT_P PR target/21801 PR target/23589 * config.gcc (i[34567]86-*-cygwin*): Add winnt-cxx.o to 'cxx_target_objs', winnt-stubs,o to 'extra_objs'.

(i386_pe_valid_dllimport_attribute_p): Define. * config/i386/winnt-cxx.c: New file. Define C++ versions of i386_pe_type_dllimport_p, i386_pe_type_dllexport_p, i386_pe_adjust_class_at_definition. * config/i386/winnt-stubs.c: New file.
