re PR inline-asm/39059 (ICE with fixed-point type in inline-asm)
PR inline-asm/39059
* c-parser.c (c_parser_postfix_expression): If fixed point is not
supported, don't accept FIXED_CSTs.
* c-decl.c (finish_declspecs): Error if fixed point is not supported
and _Sat is used without _Fract/_Accum. Set specs->type to
integer_type_node for cts_fract/cts_accum if fixed point is not
supported.
* parser.c (cp_parser_primary_expression): Reject FIXED_CSTs.
* gcc.dg/nofixed-point-2.c: New test.
* g++.dg/ext/fixed1.C: Adjust expected diagnostics.
* g++.dg/ext/fixed2.C: Likewise.
* g++.dg/other/error25.C: Likewise.
* g++.dg/lookup/crash7.C: Likewise.
* g++.dg/cpp0x/decltype-38655.C: Likewise.
