The code in mysql_create_table() code assumes that if lower_case_names==2 then table alias 
should contain unchanged table name, and this was not true for temporary tables which
had 'tmp-table' constant as alias. Now we are using table name as alias for such tables.


sql/sql_lex.cc:
  Removed tmp_table_alias constant which is no longer used.
sql/sql_lex.h:
  Removed tmp_table_alias constant which is no longer used.
sql/sql_yacc.yy:
  Let us use table name instead of 'tmp-table' as alias for table being created by 
  CREATE TEMPORARY TABLE statement. This fixes failing temp_table.test on Darwin 7.3 
  since mysql_create_table() code assumes that if lower_case_names==2 then table alias 
  should contain unchanged table name (and now this assumtion is true but it were false
  for temporary tables before...).
