This fixes the following issues: bincfg.l: In function ‘parsehex’: error: declaration of ‘val’ shadows a global declaration bincfg.y: In function ‘generate_binary_with_gbe_checksum’: error: comparison of integer expressions of different signedness bincfg.y: In function ‘yyerror’: bincfg.y:408:28: error: unused parameter ‘fp’ bincfg.y: In function ‘main’: bincfg.y:452:15: error: unused variable ‘pos’ bincfg.y:451:16: error: unused variable ‘c’ BUG=None TEST=Build outputs and make sure they're identical.
