Description:        initdb fails
Details:

I am using FAQ_CYGWIN.txt but when I follow all instructions precisely, and
perform the database initialisation as follows:

initdb -D /usr/local/pgsql/data -W -E LATIN1

the result is "initdb: failed".

So first of all, is all documentation still up to date?
Second of all, is there a workaround or some other solution for this
problem?
Third of all, "initdb:failed" is the kind of error that is too general. It
does not provide a clue of what the problem is and how to solve it.
