re PR c/13519 (typeof(nonconst+const) is const)
PR c/13519
* c-typeck.c (composite_type, common_pointer_type): New functions.
(common_type): Split parts into composite_type and
common_pointer_type. Ensure that arithmetic operations return
unqualified types without attributes. Don't make composite type
of signed enum and compatible integer be unsigned.
(build_conditional_expr, build_binary_op): Use
common_pointer_type.
* c-decl.c (merge_decls): Use composite_type.
* c-tree.h (composite_type): Declare.
testsuite:
* gcc.c-torture/enum-3.c, gcc.dg/pr13519-1.c: New tests.
