* c-decl.c (c_init_decl_processing): Set pedantic_lvalues to
true unconditionally.
* c-typeck.c (unary_complex_lvalue, pedantic_lvalue_warning):
Remove.
(build_unary_op, build_modify_expr): Don't handle extended
lvalues.
(build_component_ref, build_conditional_expr): Call non_lvalue
instead of pedantic_non_lvalue.
(build_c_cast): Don't condition use of non_lvalue on pedantic.
* fold-const.c (fold): Don't check pedantic directly for
COMPOUND_EXPR. Ensure that results for COMPOUND_EXPR are
passed to pedantic_non_lvalue.
* doc/extend.texi: Remove documentation of extended lvalues.
testsuite:
* gcc.c-torture/compile/981022-1.c: Remove.
* gcc.dg/array-5.c: Remove XFAIL.
* gcc.dg/sequence-pt-1.c: Remove test using extended lvalues.
* gcc.dg/cast-lvalue-1.c, gcc.dg/compound-lvalue-1.c,
gcc.dg/cond-lvalue-1.c: Update.
* gcc.dg/cast-lvalue-2.c: New test.
