Suppress some warnings caused by a Berkeley YACC bug/misfeature.

Berkeley YACC generates a global declaration of yylval, or the
appropriately prefixed version of yylval, in the .h file, *even though
it's been told to generate a pure parser, meaning it doesn't have any
global variables*.  Bison doesn't do this.

That causes a warning due to the local declaration in the parser
shadowing the global declaration.

So, if this is Berkeley YACC, and we have _Pragma, and have pragmas to
suppress diagnostics, we use it to turn off -Wshadow warnings.
