I've recently written to pgsql-ports about a problem with PG7.0 on NT
(Subj: [PORTS] initdb problem on NT with 7.0).  Since nobody helped me,
I had to find out the reson.  The difference between NT and Linux (for
instance) is that "open( path, O_RDWR );" opens a file in text mode.  So
sometime less block can be read than required.

I suggest a following patch.  BTW the situation appeared before, see
hba.c, pqcomm.c and others.
