two bugs in 'initdb'

First bug:

Cygwin with pgsql version: 7.4.3 ( I have gcc and ipc-daemon2 in my cygwin)

When I run 'initdb -D database', it shows:

The database cluster will be initialized with locale C

creating directory database... ok

creating directory database/base... ok

creating directory database/global... ok

creating directory database/pg_xlog... ok

creating directory database/pg_clog... ok

2. I used the 'initdb' in pgsql 7.4.3 which I downloaded from
postgresql.org:

It showed this:
