initdb crashes under Windows

Can't get the postgres server started under Win2000/cygwin. Here's
what happens:

$ initdb -D /Gauss/rr/data -W
The files belonging to this database system will be owned by user "yates".
This user must also own the server process.

The database cluster will be initialized with locale C.
