libmysql/libmysql.def:
  For to have the same order of the 3.23.XX stuff
libmysqld/lib_load.cc:
  For to have the file extension for VC++
libmysqld/lib_sql.cc:
  The VC++ compiler returns duplication define from
  net_serv.cc. If the same happens with Unix then
  those lines should be removed.
  VC++ file extension.
sql/mysqld.cc:
  Changes for Win32 Embedded Server.
sql/net_serv.cc:
  Sanja Fixes.
