Summary: Gem::Platform#=== bug - returns false when it should return true

Initial Comment:
As per IRC, this appears to be a bug:

irb(main):005:0> s1 = Gem::Platform.new(['universal', 'darwin', '9'])
=> #<Gem::Platform:0x822bac @cpu="universal", @os="darwin", @version="9">

irb(main):006:0> s2 = Gem::Platform.new(['x86', 'darwin', '8'])
=> #<Gem::Platform:0x820d02 @cpu="x86", @os="darwin", @version="8">

irb(main):007:0> s1 === s2
=> false

This caused a user on a newer version of OS X some grief when they tried to install sys-proctable, but it was failing because their platform was 'universal-darwin' but the gem is built as 'x86-darwin'.

Regards,

Dan

It is the expected behavior.

universal-darwin-9 is not compatible with universal-darwin-8

Only universal-darwin is compatible with 9 and 8.

Similar with mswin32-60 and mswin32-80 or mswin32-90, since these link to different CRT version, similar thing happens on OSX.

At least, that was the last time I've checked.

And not a minute after I posted this, I think the problem is actually the versions, i.e. 8 vs 9.

So, perhaps this is expected behavior after all.
