Description:
The generation of MAP file on Windows was removed recently (http://lists.mysql.com/commits/57778). The MAP file is currently required by the InnoDB dynamic plugin on Windows.

Vlad did suggest a workaround by using PDB file, which is also a hack, but unfortunately not a better one, IMO. After discussions, Vlad agrees to restore the MAP file in v6 release, which has no risk at all.

How to repeat:
Build mysqld from source on Windows, then check for mysqld.map file.

Suggested fix:
Restore the MAP file generation in v6.

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

       Bug#42001- restore map file generation on Windows. 
      Innodb plugin uses map files to locate address of server functions and variables by names.

OK.

This whole thing needs to go away, but requires a proper server api so plugins have access to exactly the symbols they need.

Pushed into 6.0.10-alpha (revid:alik@sun.com-20090211182317-uagkyj01fk30p1f8) (version source revid:olav@sun.com-20090113103017-41jbad7qlvlwpwxh) (merge vers: 6.0.10-alpha) (pib:6)

Noted in 6.0.10 changelog.

The MAP file was not included in Windows distribution, but is needed
by the InnoDB plugin. MAP file generation has again been enabled.
