George Koehler 59b3c10563 Use (arith) 1 << ... when getting the sign bit. ... This prevents an overflow reported by @hexcoder- in https://github.com/davidgiven/ack/issues/56 lang/cem/cpp.ansi/LLlex.c used a plain 1 << ... and caused an overflow on machines where sizeof(int) < sizeof(long). Using 1L << ... would work for now but might fail later if arith became long long. C doesn't specify whether negative integers use 2's complement or some other format. Therefore, (arith) 1 << ... has an undefined value. It should still work because the value is some integer where the sign bit is set and all other bits are clear. (unsigned arith) 1 << ... would also get the sign bit, but casting it from unsigned back to signed would make the same undefined value. (arith) -1 << ... would assume 2's complement.		2017-10-29 17:45:10 -04:00
