libmysql/libmysql.c: Fixes a very rare bug when variable name (without '_') and it's value are at the very end of the config file. I have tested it , but would liek little mobster to test it further mysql-test/r/union.result: results for union test that proves that EXPLAIN UNION bugs are fixed mysql-test/t/union.test: additional tests for EXPLAIN on UNION's that have previously failed sql/sql_yacc.yy: Some small fixes for newer parsers. Only unsigned int yystacksize remains to be fixed. This I leave to Monty. Present fixes are only aesthetic and do not harm.
