Patch BUG #5103: "pg_ctl -w (re)start" fails with custom unix_socket_directory

Hi, all

I created a pg_ctl patch to fix:
* BUG #5103: "pg_ctl -w (re)start" fails with custom unix_socket_directory 
Allow pg_ctl to work properly with configuration files located outside the PGDATA directory

I tested it under Windows XP sp3.
All of configuration files(postgresql.conf pg_hba.conf pg_ident.conf) are in c:\data,
and data_dir is in C:\Program Files\PostgreSQL\9.0\data

Check the attchment, please.

Another question, after clone source with git I can not compile them:
Bad format filename 'src\bin\scripts\submake-libpq'
Former makefile like "createdb: createdb.o ... keywords.o"
Now it is "createdb: createdb.o ... keywords.o | submake-libpq"
How to do this?
