Fixed compiler and build error:

- Fixed main.mysqlcheck error on windows
- Fixed 'can't drop database pbxt' failure when running pbxt.mysqlslap


sql/table.cc:
  When using not legal file names for checking a non existing table, one got a warning in the log file which caused mysql.mysqlcheck to fail
storage/innodb_plugin/row/row0upd.c:
  Fixed compiler warning
storage/pbxt/src/table_xt.cc:
  Remove table that is dropped from 'repair-pending'.
  Fixed 'can't drop database pbxt' failure when running pbxt.mysqlslap
