build source on windows xp

hi guys:

just downloaded mysql5.0 source, and try to build it on windows xp platform.

my tool is VC++ express 2005(free) and windows SDK.
i have successfull build most of packages, but one.

when i tried to build mysqld project, build tool always produces an error says: 

'mc' is not recognized as an internal or external command.



so my question is where is this mc tool?



regards,
