They were both undocumented and not much useful. Removal has been agreed with Mark, Miguel and MikeZ.
Removing winmysqladmin from the source (it was not included anymore in no Windows package). I'll do a test Windows noinstall.zip build before push.
MikeZ just removed mysqlshutdown and mysqlwatch from the installer scripts.

  The natural InnoDB type for NEWDECIMAL is FIXBINARY, not BINARY, since there probably is no benefit from stripping trailing bytes 0x20; note that tables created with 5.0.6 and containing DECIMAL do not need to be rebuilt, as BINARY works as well; note that because of Jani's fix to bug 10465, tables created with 5.0.? - 5.0.5 DO NEED TO BE REBUILT if they contain DECIMAL

  Added test cases for bug #9938.

The problem was that on Windows the access method indicates that access to file 
such as "com1" and "lpt1" is allowed (since they are device names) and
this causes mysql to attempt to open them as databases or tables.

The fix was to write our own my_access method that uses other Win32 functions
to determine if the given argument is indeed a file and has to requested
mode.
