Gem install fails due to invalid option

[Peter Bolier]

Hi y'll,

On attempting to install rails on a windows7 system it fails with:

H:\>gem install rails

Building native extensions.  This could take a while...

ERROR:  Error installing rails:

        ERROR: Failed to build gem native extension.

    "H:/My Programs/Ruby200-x64/bin/ruby.exe" extconf.rb

H:/My Programs/Ruby200-x64/bin/ruby.exe: invalid option -P  (-h will show valid

options) (RuntimeError)

Gem files will remain installed in H:/My Programs/Ruby200-x64/lib/ruby/gems/2.0.

0/gems/atomic-1.1.14 for inspection.

Results logged to H:/My Programs/Ruby200-x64/lib/ruby/gems/2.0.0/gems/atomic-1.1

.14/ext/gem_make.out

== 

So why does the builder use an invalid option?

Ruby version: 

H:\>ruby -v

ruby 2.0.0p247 (2013-06-27) [x64-mingw32]

Its propably something simple

My advise would be don't install rails on Windows. Use Linux (eg
Ubuntu) or Mac. If you really have not option then I believe
railsinstaller is the recommended route.
