c-decl.c (diagnose_mismatched_decls): Give error for duplicate typedefs with different but compatible types.
* c-decl.c (diagnose_mismatched_decls): Give error for duplicate
typedefs with different but compatible types. Allow duplicate
typedefs with the same type except for pedantic non-C1X, but give
warning for variably modified types.
* c-typeck.c (tagged_types_tu_compatible_p,
function_types_compatible_p, type_lists_compatible_p,
comptypes_internal): Add parameter different_types_p; set
*different_types_p for different but compatible types. All
callers changed.
(comptypes_check_different_types): New.
* c-tree.h (comptypes_check_different_types): Declare.
testsuite:
* gcc.dg/c1x-typedef-1.c, gcc.dg/c1x-typedef-2.c,
gcc.dg/c90-typedef-1.c, gcc.dg/c99-typedef-1.c: New tests.
* gcc.dg/decl-8.c: Use -std=gnu89 -pedantic-errors.
