RE: Platform string

[Ferguson, Steve]

I can't use these without having to explicitly test for each case, which
kinda defeats the point, in that I don't want to have to manually maintain
the list of operating system versions inside the configuration files.  I
envision something more like this (to use a shell metaphor):

  platform = ( `uname -sr | tr ' ' '_'`)

which is much more elegant than:

  sunos_5_6::  platform = ( sunos_5_6 )
  sunos_5_7::  platform = ( sunos_5_7 )
  sunos_5_8::  platform = ( sunos_5_8 )
  hpux...::  platform = ( hpux... )
  hpux...::  platform = ( hpux... )
  hpux...::  platform = ( hpux... )
  linux...::  platform = ( linux... )
  linux...::  platform = ( linux... )
  linux...::  platform = ( linux... )

etc.

I'm not looking for a defined class, but a defined variable that I can
insert into an expression.
