README-Windows.rdoc instructions + MSVC 9 failing to compile

Issue #235 wontfix
Nathan Bush created an issue

Trying to build the gem for Ruby 1.9.3, built with MSVC 9.

C:\Users\[user]>gem fetch pg
C:\Users\[user]>gem unpack pg-0.18.4.gem
C:\Users\[user]>cd pg-0.18.4
C:\Users\[user]\pg-0.18.4>gem install hoe rake-compiler rdoc
C:\Users\[user]\pg-0.18.4>rake --with-pg-dir=c:/PMT/PgSQL946
  invalid option: --with-pg-dir=c:/PMT/PgSQL946
C:\Users\[user]\pg-0.18.4>rake newb --with-pg-dir=c:/PMT/PgSQL946
  invalid option: --with-pg-dir=c:/PMT/PgSQL946

Rake isn't liking any options I try and pass to it.

If I try adding Postgres to PATH in console, i.e.

set PATH=C:\PMT\PgSQL946;C:\PMT\PgSQL946\bin;C:\PMT\PgSQL946\include;%PATH%

...PATH does not seem to have any positive effect.

Rake version is 10.5.0, if that makes any difference.

    You need to separate extconf options per double-dash like this: rake -- --with-pg-dir=...

    Look into the mkmf.log file, that is mentioned in the output, to diagnose extconf issues.

    Unfortunately none of the ruby-pg maintainers uses MSVC with Ruby. So, we are pleased to receive pull requests, but don't do regular tests on that platform.
