Changes in version 1.875d:
* Unescaped newlines are no longer allowed in character constants or
string literals. They were never portable, and GCC 3.4.0 has
dropped support for them. Better diagnostics are now generated if
forget a closing quote.
* NUL bytes are no longer allowed in Bison string literals, unfortunately.
* %token numbers can now be hexadecimal integers, e.g., `%token FOO 0x12d'.
This is a GNU extension.
* A new directive "%expect-rr N" specifies the expected number of
reduce/reduce conflicts in GLR parsers.
* Experimental %destructor support has been added to lalr1.cc.
